Subject [jira] [Commented] (HDFS-7729) Add logic to DFSOutputStream to support writing a file in striping layout
Date Thu, 05 Mar 2015 00:14:38 GMT

    [ https://issues.apache.org/jira/browse/HDFS-7729?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14347819#comment-14347819
] 

Zhe Zhang commented on HDFS-7729:
---------------------------------

In my tests I set {{cellSize}} to a smaller value (1024) and got IndexOutOfBound error in
{{encode}}. [~libo-intel] could you take a look when you resume work on this JIRA (after HDFS-7793)?

> If client wants to directly write a file striping layout, we need to add some logic to
DFSOutputStream.  DFSOutputStream needs multiple DataStreamers to write each cell of a stripe
to a remote datanode.
