----------------------------------------
Assignee: Pracheer Agarwal
> Catch the "permission denied Exception" while deleting an entity
> ----------------------------------------------------------------
>
> Key: FALCON-2212
> URL: https://issues.apache.org/jira/browse/FALCON-2212
> Project: Falcon
> Issue Type: Improvement
> Reporter: Pracheer Agarwal
> Assignee: Pracheer Agarwal
>
> Current Behaviour:
> While deleting an entity, falcon currently is throwing exception(permission
> denied Exception) thrown by HDFS. It does not look neat on CLI.
> Stacktrace:
> {noformat}
> ERROR: Bad Request;clusterName/Failed to cleanup entity path for (process)
> processName on cluster clusterName
> CausedBy: Permission denied: user=pracheer.agarwal, access=ALL,
> inode="/projects/ivory/staging/falcon/workflows/process/processName":falcon:supergroup:drwxr-xr-x

> Desired Behaviour:
> Catch that exception and wrap it under FalconException and show a meaningful
> error message.
