[jira] Updated: (HADOOP-3814) [HOD] Remove dfs.client.buffer.dir generation, as this is removed in Hadoop 0.19.

     [ https://issues.apache.org/jira/browse/HADOOP-3814?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Vinod K V updated HADOOP-3814:
------------------------------

    Attachment: HADOOP-3814-20081010.txt

Attaching a patch. This removes dfs.client.buffer.dir generation by HOD. The parameter's actual usage is given up in HADOOP-0.16 itself, which is three versions far from 0.19; no backwards compatibility.

Besides HOD, I can still see other references to the parameter - in comments of Configuration.java (+100), LocalDirAllocator.java(+66) and also generated in the test case TestLocalDirAllocator.java.

> In HADOOP-3756, the dfs.client.buffer.dir parameter was removed from hadoop-default.xml, as this was no longer used. HOD generates this parameter in the hadoop-site it generates. This must be removed as well.
