Subject [jira] Commented: (MAPREDUCE-1614) TestDFSIO should allow to configure output directory
Date Wed, 05 May 2010 19:19:03 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1614?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12864458#action_12864458

Konstantin Boudnik commented on MAPREDUCE-1614:
-----------------------------------------------

.bq Specifying "test.build.data" changes the output directory for TestDFSIO. -Dtest.build.data
probably doesn't work, as this parameter should be configured.

Yes, setting this parameter does not do any good - I still can see that {{Permission denied:
user=cos, access=WRITE, inode="":hdfs:hdfs:rwxr-xr-x}} issue

> TestDFSIO has a hardcoded location for its files to be written and read to or from. This
location is /benchmarks. However, it might pose a problem if HDFS '/' doesn't allow anyone
to write into it. It'd be convenient to have a command line option to specify an alternative
location on demand.
