# 在 Amazon EMR 叢集上安裝其他軟體
<a name="emrcluster-example-install-software"></a>

**Example**  <a name="example2"></a>
`EmrCluster` 提供在 Amazon EMR 叢集上安裝第三方軟體`supportedProducts`的欄位，例如，它可讓您安裝自訂 Hadoop 分佈，例如 MapR。它接受要讀取及採取動作的第三方軟體引數逗號分隔清單。以下範例會示範如何使用 `EmrCluster` 的 `supportedProducts` 欄位建立自訂 MapR M3 版本叢集，在其上安裝 Karmasphere Analytics，並在其上執行 `EmrActivity` 物件。  

```
{
    "id": "MyEmrActivity",
    "type": "EmrActivity",
    "schedule": {"ref": "ResourcePeriod"},
    "runsOn": {"ref": "MyEmrCluster"},
    "postStepCommand": "echo Ending job >> /mnt/var/log/stepCommand.txt",    
    "preStepCommand": "echo Starting job > /mnt/var/log/stepCommand.txt",
    "step": "/home/hadoop/contrib/streaming/hadoop-streaming.jar,-input,s3n://elasticmapreduce/samples/wordcount/input,-output, \
     hdfs:///output32113/,-mapper,s3n://elasticmapreduce/samples/wordcount/wordSplitter.py,-reducer,aggregate"
  },
  {    
    "id": "MyEmrCluster",
    "type": "EmrCluster",
    "schedule": {"ref": "ResourcePeriod"},
    "supportedProducts": ["mapr,--edition,m3,--version,1.2,--key1,value1","karmasphere-enterprise-utility"],
    "masterInstanceType": "m3.xlarge",
    "taskInstanceType": "m3.xlarge"
}
