[jira] Commented: (HADOOP-1875) multiple dfs.client.buffer.dir directories are not treated as alternatives

["Raghu Angadi (JIRA)" <ji...@apache.org>]

Raghu Angadi commented on HADOOP-1875:
--------------------------------------


DFS client uses {{LocalDirAllocator.createTmpFileWrite()}}

{{LocalDirAllocator}} explicitly states that it does not check for write permissions. I think it should try different directory when create on one dir fails (for whatever reason).

Also during initialization it ignores the error while trying to {{mkdirs(dir[i])}}.

> When specifying multiple directories in the value for dfs.client.buffer.dir, jobs fail when the selected directory does not exist or is not writable. Correct behaviour should be to create the directory when it does not exist and fail over to an alternative directory when it is not writable.
