Description

• Include proc_<processname> in cli, beeline, metastore, hs2 process args
• LLAP history logger - log QueryId instead of dagName (dag name is free flowing text)
• LLAP JXM ExecutorStatus - Log QueryId instead of dagName. Sort by running / queued
• Include thread name in TaskRunnerCallable so that it shows up in stack traces (will cause extra output in logs)
