[jira] [Commented] (HBASE-22280) Separate read/write handler for
priority request(especially for meta).
[ https://issues.apache.org/jira/browse/HBASE-22280?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17313454#comment-17313454 ]
Huaxiang Sun commented on HBASE-22280:
--------------------------------------
Hi [~binlijin], do you run into production issue without this change? Can you share more info?
We are seeing a meta throughput regression from hbase-1 to hbase-2, due to rpc scheduler change.
Changing back to FastPathBalancedQueueRpcExecutor for priority rpc queue removes the regression.
