Description

LevelDBCacheTimelineStore requires jackson-databind-2.2.3.jar which is in $HADOOP_HOME/share/hadoop/tools/lib but is never added in timeline server's classpath. Reading data from LevelDBCacheTimelineStore will get NoClassDefFoundError. Here's the stacktrace:

A temporary fix would be adding $HADOOP_HOME/share/hadoop/tools/lib/* into HADOOP_CLASSPATH manually.
