Github user zjffdu commented on the pull request: https://github.com/apache/spark/pull/9134#issuecomment-150392534 Here's how to reproduce the issue. 1. export SPARK_PREPEND_CLASSES=true 2. Build spark with command: build/sbt assembly -Pyarn -Phadoop-2.6 -Phive -Phive-thriftserver 3. Build spark again with command: build/sbt assembly -Pyarn -Phadoop-2.6 4. Start spark-sql: bin/spark-sql The root cause is that we still have SparkSQLCLIDriver in classpath (under sql/hive-thriftserver/target). But we don't have hive related classes in classpath.
