My ambari metrics collector always goes down after running one or two days.
From the ambari metrics collector log, I find following message:
java.sql.SQLException: Encountered exception in a sub plan[0] execution
.....
caused by: java.sql.SQLException:Encountered exception in sub plan[0] execution
...
caused by java.sql.SQLException: java.util.concurrent.TimeoutException
at orig.apache.phoenix.cache.ServerCacheClient.addServerCache...
It seems be related to phoenix. But from hbase page on ambari, I have no phoenix server.
The mode is distributed.
