[jira] [Issue Comment Deleted] (OOZIE-2768) Oozie workflow goes into suspended state with JA009: Output directory already exists

Abhishek Bafna updated OOZIE-2768:
----------------------------------
    Comment: was deleted

(was: Oozie action directory: 
{code}
String name = getWorkflow().getId() + "/" + action.getName() + "--" + action.getType();
{code}

The cleanup of the action directory is not happening correctly. Though Oozie workflow cleanup the directory when the action completes or workflow (or action) is killed.

During the workflow action setup Oozie checks for the existence for the directory and if not present then creates them. The 'output' is set as part of the launcher configuration.

{code}
launcherConf.set("mapred.output.dir", new Path(actionDir, "output").toString());
{code}

We should do either of these:
* In case when the action directory is already present, It should cleanup and re-create the action directory.
* While setting up the 'output' directory check its existence and delete if already exists.

I would prefer the first approach. Thanks.)
