Subject [jira] [Commented] (HBASE-9139) Independent timeout configuration for rpc channel between cluster nodes
Date Mon, 12 Aug 2013 17:20:48 GMT

    [ https://issues.apache.org/jira/browse/HBASE-9139?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13737065#comment-13737065

stack commented on HBASE-9139:

+1  Looks like this rpc is only for reporting master status

The failed unit test is TestAdmin; it is missing in list of tests.  I'm guessing it is the
testTableExists test that is failing.

> Default of "hbase.rpc.timeout" is 60000 ms (1 min). User sometimes
> increase them to a bigger value such as 600000 ms (10 mins) for many
> concurrent loading application from client. Some user share the same
> hbase-site.xml for both client and server. HRegionServer
> #tryRegionServerReport via rpc channel to report to live master, but
> there was a window for master failover scenario. That region server
> attempting to connect to master, which was just killed, backup master
> took the active role immediately and put to /hbase/master, but region
> server was still waiting for the rpc timeout from connecting to the dead
> master. If "hbase.rpc.timeout" is too long, this master failover process
> will be long due to long rpc timeout from dead master.
> If so, could we separate with 2 options, "hbase.rpc.timeout" is still
> for hbase client, while "hbase.rpc.internal.timeout" was for this
> regionserver/master rpc channel, which could be set shorted value
> without affect real client rpc timeout value?
