Subject [jira] [Commented] (HAMA-673) Integrate new service layers
Date Tue, 04 Feb 2014 12:28:09 GMT

    [ https://issues.apache.org/jira/browse/HAMA-673?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13890609#comment-13890609

Skater Xu commented on HAMA-673:

The HDFS2.x problem is caused by the protobuffer version.
After I upgrade protobufer2.4a.jar to protobuf-java-2.5.0.jar in $hamahome/lib, that problem
is gone(So it should relate to mavn build issue, do I need to log an issue and fix it there?)
And after fix hdfs, zookeeper has error now

org.apache.zookeeper.KeeperException$ConnectionLossException: KeeperErrorCode = ConnectionLoss
