Hi Anthony, We have HADOOP_CLASSPATH setup in Ambari. Mainly you need tez client on Hive server and Tez libraries should be setup in HADOOP_CLASSPATH. This is what we have: ======================== export HADOOP_CLASSPATH=${HADOOP_CLASSPATH}${JAVA_JDBC_LIBS}:${MAPREDUCE_LIBS} if [ -d "/usr/lib/tez" ]; then export HADOOP_CLASSPATH=$HADOOP_CLASSPATH:/usr/lib/tez/*:/usr/lib/tez/lib/*:/etc/tez/conf fi ======================== Please let me know if this helps you.

We managed to resolve this issue by installing Tez client on hive server2 and setting up HADOOP_CLASSPATH accordingly. Hive server needs to be restarted after making all the changes and then we are able to run queries using Tez.

Hi All, I am trying to connect to hive using jdbc connection string and modified the execution engine to tez. I get below error: org.apache.hive.service.cli.HiveSQLException: java.lang.NoClassDefFoundError: org/apache/tez/runtime/api/Event: org.apache.tez.runtime.api.Event Connection string is: jdbc:hive2://XXX.XX.XXX.XX:10001/dbname;transportMode=http;httpPath=cliservice?hive.execution.engine=tez;tez.queue.name=q1; Can you help me how I can solve this error? Also please let me know if I need additional jar files for this to work? This works fine when execution engine is map reduce. However, I have to make it working with Tez for better performance. Thanks in advance for your advise. Regards, Tushar
