Subject [jira] [Commented] (HBASE-15948) Port "HADOOP-9956 RPC listener inefficiently assigns connections to readers"
Date Fri, 03 Jun 2016 01:18:59 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15948?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15313437#comment-15313437

Enis Soztutar commented on HBASE-15948:
---------------------------------------

My reading of the Selector javadoc is that Selector.register() and select() are thread-safe.
Is it not the case? 
{quote} Selectors are themselves safe for use by multiple concurrent threads; their key sets,
however, are not. {quote}
If not, the patch makes sense.

> Esteban noticed we were missing this upstream issue. Seems to make no difference in profiling
but here is the patch anyways.
