# Diferencias en la versiones de lanzamiento de Amazon EMR 4.x
<a name="emr-release-differences-4x"></a>

La documentación de las características de Amazon EMR en la *Guía de administración de Amazon EMR* especifica la versión de Amazon EMR en la que una característica está disponible, así como las diferencias correspondientes entre las características de Amazon EMR que se remontan a la versión 4.0.0.

A partir de la versión 5.0.0 de Amazon EMR, algunas aplicaciones obtuvieron una actualización de versión importante que cambió los detalles de instalación y de su funcionamiento, y otras pasaron de ser aplicaciones de entorno aislado a aplicaciones nativas. Cada tema de esta sección indica las diferencias importantes específicas de la aplicación cuando se utilizan las versiones 4.x de Amazon EMR.

# Aplicaciones de entorno aislado
<a name="emr-sandbox-apps-4x"></a>

Cuando se utilizan las versiones 4.x de Amazon EMR, algunas aplicaciones se consideran aplicaciones de *entorno aislado*. Las aplicaciones de entorno aislado son versiones preliminares de la aplicación que se publicaron durante el lanzamiento inicial de Amazon EMR debido a la demanda. Puede usar la consola o la API para que Amazon EMR instale las aplicaciones de entorno aislado de la misma manera que las aplicaciones nativas, pero las aplicaciones de entorno aislado tienen soporte y documentación limitados. AWS CLI Las aplicaciones de entorno aislado se convirtieron en aplicaciones nativas totalmente compatibles en la versión de lanzamiento de Amazon EMR 5.0.0 y posteriores. A continuación, se indican las aplicaciones de entorno aislado en las versiones de lanzamiento de Amazon EMR 4.x:
+ Oozie
+ Presto
+ Sqoop
+ Zeppelin
+ ZooKeeper

Al instalar las aplicaciones del entorno de pruebas, los nombres de las aplicaciones se indican con el sufijo `-sandbox`. Por ejemplo, para instalar la versión sandbox de, utilice. *Presto* `Presto-sandbox` La instalación puede tardar más que para una aplicación totalmente compatible. El número de versión indicado para cada aplicación en esta sección se corresponde con la versión de la comunidad de la aplicación.

## Oozie (versiones de entorno aislado)
<a name="emr-Oozie-sandbox-4x"></a>

Oozie está disponible como una aplicación de entorno aislado a partir de la versión 4.1.0 de Amazon EMR.

Los ejemplos de Oozie no se instalan de forma predeterminada con las versiones del entorno de pruebas. Para instalar los ejemplos, conéctese con SSH al nodo principal y ejecute `install-oozie-examples`.

# Consideraciones sobre el uso de Hive en Amazon EMR 4.x
<a name="emr-Hive-4x"></a>

En esta sección, se abordan las diferencias que deben tenerse en cuenta cuando se utiliza Hive versión 1.0.0 en las versiones 4.x de Amazon EMR, en comparación con Hive 2.x en las versiones 5.x de Amazon EMR.

## No se admiten las transacciones ACID
<a name="emr-Hive-acid-4x"></a>

Hive en las versiones 4.x de Amazon EMR no admite las transacciones ACID con datos de Hive almacenados en Amazon S3 cuando se utilizan las versiones 4.x. Si intenta crear una tabla de transacciones en Amazon S3, se produce una excepción.

## Lectura y escritura en tablas de Amazon S3
<a name="emr-Hive-s3table-4x"></a>

Hive en las versiones 4.x de Amazon EMR puede escribir directamente en Amazon S3 sin utilizar archivos temporales. De esta forma se mejora el rendimiento, pero también impide que se pueda leer y escribir en la misma tabla de Amazon S3 dentro de la misma instrucción de Hive. Una solución consiste en crear y utilizar una tabla temporal en HDFS.

El siguiente ejemplo muestra cómo utilizar varias instrucciones de Hive para actualizar una tabla en Amazon S3. Las instrucciones crean una tabla temporal en HDFS denominada `tmp` con base en una tabla de Amazon S3 denominada `my_s3_table`. A continuación, la tabla de Amazon S3 se actualizará con el contenido de la tabla temporal.

```
CREATE TEMPORARY TABLE tmp LIKE my_s3_table;
INSERT OVERWRITE TABLE tmp SELECT ....;
INSERT OVERWRITE TABLE my_s3_table SELECT * FROM tmp;
```

## Log4j y Log4j 2
<a name="emr-Hive-log4j-4x"></a>

Hive en las versiones de lanzamiento de Amazon EMR 4.x utiliza Log4j. A partir de la versión 5.0.0, se utiliza Log4j 2 de forma predeterminada. Estas versiones pueden requerir diferentes configuraciones del registro. Consulte [Apache Log4j 2](http://logging.apache.org/log4j/2.x/) para obtener más información.

## MapReduce es el motor de ejecución por defecto
<a name="emr-Hive-tez-4x"></a>

Las versiones 4.x de Hive on Amazon EMR MapReduce utilizan como motor de ejecución predeterminado. A partir de la versión 5.0.0 de Amazon EMR, se utiliza Tez de forma predeterminada, que proporciona un mejor rendimiento para la mayoría de los flujos de trabajo.

## Autorización de Hive
<a name="emr-Hive-authz-4x"></a>

Hive en las versiones de lanzamiento de Amazon EMR 4.x admite [Autorización de Hive](https://cwiki.apache.org/confluence/display/Hive/LanguageManual+Authorization) para HDFS, pero no para EMRFS y Amazon S3. Los clústeres de Amazon EMR se ejecutan con la autorización desactivada de forma predeterminada.

## Comportamiento de combinación de archivos de Hive con Amazon S3
<a name="emr-Hive-filemerge-4x"></a>

Hive en las versiones 4.x de Amazon EMR combina archivos pequeños al final de un trabajo de solo asignación si `hive.merge.mapfiles` es `true`. La combinación solo se activa si el tamaño de salida medio del trabajo es menor que el valor de `hive.merge.smallfiles.avgsize`. Hive en Amazon EMR tiene exactamente el mismo comportamiento si la ruta de salida final se encuentra en HDFS. Sin embargo, si la ruta de salida se encuentra en Amazon S3, se omite el parámetro `hive.merge.smallfiles.avgsize`. En esta situación, la tarea de combinación siempre se activa si `hive.merge.mapfiles` está definido en `true`.

# Consideraciones sobre el uso de Pig en Amazon EMR 4.x
<a name="emr-Pig-4x"></a>

La versión 0.14.0 de Pig se instala en los clústeres creados con versiones 4.x de Amazon EMR. Pig se ha actualizado a la versión 0.16.0 en la versión 5.0.0 de Amazon EMR. Las diferencias significativas se explican a continuación.

## Motor de ejecución predeterminado diferente
<a name="emr-Pig-engine-4x"></a>

La versión 0.14.0 de Pig en las versiones 4.x de Amazon EMR utiliza MapReduce como motor de ejecución predeterminado. Pig 0.16.0 y versiones posteriores utilizan Apache Tez. Puede establecer de forma explícita la clasificación de `pig-properties` configuración que `exectype=mapreduce` se va a utilizar. MapReduce

## Funciones definidas por el usuario de Dropped Pig () UDFs
<a name="emr-Pig-udf-4x"></a>

Las versiones personalizadas UDFs que estaban disponibles en las versiones 4.x de Pig on Amazon EMR se eliminaron a partir de Pig 0.16.0. La mayoría de ellas UDFs tienen funciones equivalentes que puede utilizar en su lugar. En la siguiente tabla se enumeran las funciones UDFs omitidas y las equivalentes. Para más información, consulte [Funciones integradas](https://pig.apache.org/docs/r0.16.0/func.html) en el sitio de Apache Pig.

## Comandos de Grunt suspendidos
<a name="emr-pig-gruntcmd-4x"></a>

Algunos comandos de Grunt se han dejado de utilizar a partir de Pig 0.16.0. En la siguiente tabla, se muestran comandos de Grunt en Pig 0.14.0 y los comandos equivalentes en la versión actual, si procede. 


**Pig 0.14.0 y los comandos equivalentes de Grunt actuales**

## Se ha eliminado la capacidad de directorios de inicio que no son de HDFS
<a name="emr-Pig-users-4x"></a>

Pig 0.14.0 en las versiones 4.x de Amazon EMR tiene dos mecanismos que permiten a los usuarios distintos del usuario `hadoop`, que no tienen directorios de inicio, ejecutar scripts de Pig. El primer mecanismo es una reserva automática que establece el directorio de trabajo inicial en el directorio raíz si el directorio de inicio no existe. El segundo es una propiedad `pig.initial.fs.name` que le permite cambiar el directorio de trabajo inicial.

Estos mecanismos no están disponibles a partir de la versión 5.0.0 de Amazon EMR y los usuarios deben tener un directorio de inicio en HDFS. Esto no se aplica al usuario de `hadoop`, ya que se aprovisiona un directorio de inicio en el lanzamiento. La ejecución de scripts con pasos de Hadoop jar adopta de manera predeterminada el usuario de Hadoop, a menos que se especifique otro usuario mediante `command-runner.jar`.
