Subject [jira] [Commented] (HDFS-3620) WebHdfsFileSystem getHomeDirectory() should not resolve locally
Date Fri, 25 Jan 2013 19:49:12 GMT

    [ https://issues.apache.org/jira/browse/HDFS-3620?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13562957#comment-13562957
] 

Alejandro Abdelnur commented on HDFS-3620:
------------------------------------------

If the target FS has home dirs in other location than '/user/<UID>' then WebHdfsFileSystem
will return the incorrect value.

To avoid perf issues, this call should be done ONCE per WebHdfsFilesystem and cached in the
instance.

> WebHdfsFileSystem getHomeDirectory() method it is hardcoded to return '/user/' + UGI#shortname.
Instead, it should make a HTTP REST call with op=GETHOMEDIRECTORY.
