Subject [jira] [Updated] (HDFS-2298) TestDfsOverAvroRpc is failing on trunk
Date Wed, 28 Sep 2011 19:38:45 GMT

     [ https://issues.apache.org/jira/browse/HDFS-2298?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Doug Cutting updated HDFS-2298:
-------------------------------

    Attachment: HDFS-2298.patch

Here's a patch that fixes one issue, where someone introduced a new call that needed to be
renamed.  But, even with this, this patch no longer works.  I believe the problem is due to
something in HADOOP-7524.  The AvroProtocolEngine on the namenode no longer responds using
the right protocol when the DataNode contacts it with datanodeVersionRequest.  It tries to
respond with ClientProtocol rather than DatanodeProtocol.  I'll try to look into this more.
 Sanjay, do you have any idea what's going on here?
