**Amazon EMR 6.9.0 - Tez known issues**
+ **Hive jobs running on Tez** – In clusters with SSL enabled running EMR version 6.9.0, there is a known issue where Hive jobs running on Tez fail with *SSLHandshakeException*. This is related to the open-source issue [TEZ-4096](https://issues.apache.org/jira/browse/TEZ-4096), which was introduced with the Tez upgrade to version 0.10.2 in EMR 6.9.0. The issue requires SSL-related configurations to be passed from the client side (Hive).

  **Fix version:** – EMR 6.10.0

  **Workaround** – Add the following SSL configuration to tez-site.xml:

  </property>
