Michael Stack created HBASE-25735: ------------------------------------- Summary: Add target Region to connection exceptions Key: HBASE-25735 URL: https://issues.apache.org/jira/browse/HBASE-25735 Project: HBase Issue Type: Bug Components: rpc Reporter: Michael Stack Assignee: Michael Stack
We spent a bit of time making it so exceptions included the remote host name. Looks like we can add the target Region name too with a bit of manipulation; will help figuring hot-spotting or problem Region on serverside. For example, here is what I was seeing recently on client-side when a RS was was timing out requests: {code} 2021-04-06T02:18:23.533Z, RpcRetryingCaller{globalStartTime=1617675482894, pause=100, maxAttempts=4}, org.apache.hadoop.hbase.ipc.CallTimeoutException: Call to ps0989.example.org/1.1.1.1:16020 failed on local exception: org.apache.hadoop.hbase.ipc.CallTimeoutException: Call[id=88369369,methodName=Get], waitTime=5006, rpcTimeout=5000 at org.apache.hadoop.hbase.client.RpcRetryingCallerImpl.callWithRetries(RpcRetryingCallerImpl.java:145) at org.apache.hadoop.hbase.client.HTable.get(HTable.java:383) at org.apache.hadoop.hbase.client.HTable.get(HTable.java:357) ...

I wanted to know if it was a server problem or a Region issue. If clients only having issue w/ one Region, then I could focus on it. After the PR the exception (from another context) looks like this: {code} org.apache.hadoop.hbase.ipc.CallTimeoutException: Call to address=127.0.0.1:12345, regionInfo=hbase:meta,,1.1588230740 failed on local exception: org.apache.hadoop.hbase.ipc.CallTimeoutException: error .... {code} -- This message was sent by Atlassian Jira (v8.3.4#803005)
