[jira] [Commented] (HIVE-2400) Update unittests Hadoop version

    [ https://issues.apache.org/jira/browse/HIVE-2400?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13093907#comment-13093907 ] 

Ning Zhang commented on HIVE-2400:
----------------------------------

+1 on upgrading to a higher hadoop version. It seems the apache repo only hold upto 0.20.3. Maybe we need to upgradt to that version. Also we'll need to upgrade all the mirrows (facebook and cloudera's). 

Any other thoughts?

> Hadoop 0.20.1 used in unittests contains bugs that were fixed in later versions of Hadoop, for example
> * har:// connections cannot be indexed by (scheme, authority, username) - the path is significant as well. Caching them in this way limits a hadoop client to opening one archive per filesystem. It seems to be safe not to cache them, since they wrap another connection that does the actual networking.
> fixed in https://issues.apache.org/jira/browse/HADOOP-6231 .
