Known Issues in Apache Hadoop
This topic describes known issues and workarounds for using Hadoop in this release of Cloudera Runtime.
- Hive on Tez cannot run certain queries on tables stored in encryption zones. This occurs when KMS connection is SSL encrypted and a self-signed certificate is used. You may see SSLHandshakeException in Hive logs in this case.
- There are two workarounds: 1. You can install a self-signed SSL certificate into cacerts file in all hosts. 2. You can copy ssl-client.xml to a directory that is available in all hosts. Then you must set the tez.aux.uris=path-to-ssl-client.xml property in Hive on Tez advanced configuration.
