Description

wrap jdbc split

allow zero split returns in llapdump

allow setting of llap output format as file format option

create job conf via dag utils

JDCB LlapInputSplit should not be an inner class

Hack: Spark uses hive-1.2.1, which does not have HiveConf.ConfVars.LLAP_DAEMON_RPC_PORT, use "hive.llap.daemon.rpc.port"

• Use Class.getName() rather than Class.toString() for class name
• Add LlapInputSplit Writable test

Fix for filesink operator close NPE.
