Date Sat, 22 Oct 2011 06:04:32 GMT

     [ https://issues.apache.org/jira/browse/HDFS-2452?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Uma Maheswara Rao G updated HDFS-2452:
--------------------------------------

    Attachment: HDFS-2452-Trunk.patch

Here is a patch for trunk with test.
1. In trunk code, InputStream getting logic has been moced to DataXceiver constructor. So,
we need to stub getInputStream also.Updated with this change in test.

Thanks
Uma
