Subject [jira] [Commented] (HADOOP-8227) Allow RPC to limit ephemeral port range.
Date Fri, 30 Mar 2012 16:00:34 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8227?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13242483#comment-13242483

Robert Joseph Evans commented on HADOOP-8227:

Unfortunately for 0.23 the RPC engine code is split among the projects so the patches for
MAPREDUCE-4079 and HADOOP-8227 need to go in at the same time.  I have attached the full patch
for branch-0.23 at https://issues.apache.org/jira/secure/attachment/12520617/MR-4079-full-branch-0.23.txt
for both of these JIRAs.  Once both JIRAs are approved for trunk and branch-2.0, I can put
the full patch into branch-0.23.

range of ports that are used when some RPC servers select a port.
