PhoenixToElasticSearchJob Fails with "Multiple ES-Hadoop versions detected in the classpath"

This error can occur if the Data Node Directories defined in HDFS's configuration in Ambari point to a symlink. YARN will attempt to resolve this symlink, as well as the real path, and will result in 2 JAR files being found in the classpath, causing this error.

To resolve this issue, ensure that you are not using symlinks in any locations that lead to, or contain, your HDFS Data Node Directories.
