Josh Elser commented on HBASE-13351: ------------------------------------ WFM, I've been waffling about whether or not this will actually have a perceived difference (for the end-user/admin). I feel like if the master's handler threads are saturated, the fact that RS can still chat with the master won't really matter. Ultimately, I think HBASE-13375 would have a much bigger positive impact than this, but these changes do have some net-positive effect. > Annotate internal MasterRpcServices methods with admin priority > --------------------------------------------------------------- > > Key: HBASE-13351 > URL: https://issues.apache.org/jira/browse/HBASE-13351 > Project: HBase > Issue Type: Improvement > Components: master > Reporter: Josh Elser > Assignee: Josh Elser > Fix For: 2.0.0, 1.1.0 > > Attachments: HBASE-13351-v1.patch, HBASE-13351.patch > > > HBASE-12071, among other things, introduced annotating RPC methods to give > certain methods priority over others. Namely, this helps ensure that client > requests cannot starve out internal RPC between master and regionserver. > Similarly, we can do the same thing for Master RPC methods that are invoked > by RS's. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
