Subject [jira] Commented: (HDFS-1310) TestFileConcurrentReader fails
Date Wed, 01 Sep 2010 04:22:58 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1310?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12904897#action_12904897
] 

sam rash commented on HDFS-1310:
--------------------------------

The problem is due to a couple of issues

1. DFSInputStream was doing a Datanode RPC to get the block length of an in-progress file;
it  created a proxy object that was not shutdown
2. even calling RPC.stopProxy() in DFSInputStream.readBlockLength() failed due to a faulty
hashcode() function in ConnectionId.  This will be fixed in  https://issues.apache.org/jira/browse/HADOOP-6907

In the meantime, there is one patch for hdfs, and hadoop common will also need HADOOP-6907
before this will not timeout

I will upload the patch for hdfs shortly
