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.
