[solution]

Reason: the jline version in YARN is too low.

Copy the jline package from the ${hive_home} / lib directory to the ${hadoop_home} / share/hadoop/yarn/lib directory and start hive.

Solution: replace the jline in hive-lib with the yarn-lib directory:

Cp $HIVE_HOME/lib/jline-2.12.jar $HADOOP_HOME/share/hadoop/yarn/lib/

Rm-f $HADOOP_HOME/share/hadoop/yarn/lib/jline-0.9.94.jar
