Subject [jira] [Reopened] (HBASE-13647) Default value for hbase.client.operation.timeout is too high
Date Fri, 29 May 2015 19:33:18 GMT

     [ https://issues.apache.org/jira/browse/HBASE-13647?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Enis Soztutar reopened HBASE-13647:
-----------------------------------

Reopening this since there are a couple of problems. 

It seems that it has been committed to 0.98+. But I don't think it is appropriate for 1.0.x,
and 1.1.x. Since the default value goes from int max to 60 sec which is a very aggressive
change. In case the zookeeper session timeout is larger than >60 sec, this will cause all
RPCs to fail in case of a RS crash. We have seen this happening in our test rig a lot. The
region cannot be assigned unless ZK session timeout (which 90 sec by default) have expired
and regions are assigned back again. The 35 retries by default with the operation timeout
used to override this. 

I'll revert this change from all branches, until we have a conclusion for the next steps.
The 0.98.13RC contains the patch. I'll update the thread. 

Also, please remember to set the fix versions appropriately when the issue is committed.

> Default value for hbase.client.operation.timeout is too high, it is LONG.Max.
> That value will block any service calls to coprocessor endpoints indefinitely.
> Should we introduce better default value for that?
