Our streaming job run into trouble in these days after a long time smooth running. One issue we found is [#FLINK-8019] and another one is this one. After analyzing the jstack, we believe we found a DEAD LOCK in flink: 1. The thread "cache-process0 -> async-operator0 -> Sink: hbase-sink0 (8/8)" hold lock 0x00000007b6aa1788 and is waiting for lock 0x00000007b6aa1940. 2. The thread "Time Trigger for cache-process0 -> async-operator0 -> Sink: hbase-sink0 (8/8)" hold lock 0x00000007b6aa1940 and is waiting for lock 0x00000007b6aa1788. This DEADLOCK made the job fail to proceed. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
