Subject [jira] [Updated] (HBASE-11297) Remove some synchros in the rpcServer responder
Date Wed, 25 Jun 2014 16:04:25 GMT

     [ https://issues.apache.org/jira/browse/HBASE-11297?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Andrew Purtell updated HBASE-11297:

Although ConcurrentLinkedDeque does not use any Unsafe methods not available in the 6 runtime,
we cannot clone the source from the JDK into our distribution for JRE < 7 because OpenJDK
is GPL 2.

Changing the patch to use another data structure invalidates the performance analysis done
on this issue.

Therefore sadly let's not include this in 0.98. Supporting JDK >= 7 only for trunk sounds
reasonable to me. We should discuss it on dev@. Depending on the outcome of that discussion
amending trunk may not be necessary.
