Subject [jira] [Commented] (HADOOP-7380) Common portion of HDFS-1973
Date Wed, 15 Jun 2011 23:04:48 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7380?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13050104#comment-13050104

Aaron T. Myers commented on HADOOP-7380:

Another open issue which needs to be addressed is synchronization around the {{FailoverProxyProvider}}
on failover. This will be necessary since multiple threads may be accessing a single RPC proxy,
and we don't want this to effectively cause the client to failover multiple times spuriously.

I'll deal with this once I get confirmation that the general approach is sound.
