Subject [jira] [Commented] (HBASE-6441) MasterFS doesn't set scheme for internal FileSystem
Date Fri, 14 Sep 2012 14:46:07 GMT

    [ https://issues.apache.org/jira/browse/HBASE-6441?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13455833#comment-13455833

Jonathan Hsieh commented on HBASE-6441:

i was trying to get the 0.94 and trunk builds to work against hadoop 2.0 a while back and
had a problem with TestImportExport.  (I believe writes went to one local fs and reads went
to hdfs or vice versa.).  I had a gross hack that made the test pass but I never got to the
point understanding why it worked so I didn't commit it.

> FSUtils.getRootDir() just takes a configuration object, which is used to:
> 1) Get the name of the root directory
> 2) Create a filesystem (based on the configured scheme)
> 3) Qualify the root onto the filesystem
> However, the FileSystem from the master filesystem won't generate the correctly qualified
root directory under hadoop-2.0 (though it works fine on hadoop-1.0). Seems to be an issue
with the configuration parameters.
