Nicolas Liochon commented on HBASE-9139: ---------------------------------------- I agree. It's great it's so simple at the end. Just one thing I forgot on my previous review: could you add this setting in hbase-common/main/resources/hbase-default.xml (next to the existing hbase.rpc.timeout), with a nice explanation of what it does? Thanks a lot, Julian. > Independent timeout configuration for rpc channel between cluster nodes > ----------------------------------------------------------------------- > > Key: HBASE-9139 > URL: https://issues.apache.org/jira/browse/HBASE-9139 > Project: HBase > Issue Type: Improvement > Components: IPC/RPC, regionserver > Affects Versions: 0.94.10, 0.96.0 > Reporter: Julian Zhou > Assignee: Julian Zhou > Priority: Minor > Fix For: 0.94.12, 0.96.0 > > Attachments: 9139-0.94-v0.patch, 9139-trunk-v0.patch > > > Default of "hbase.rpc.timeout" is 60000 ms (1 min).

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? -- This message is automatically generated by JIRA.
