> Provide server-side error details on CLI, if any
> ------------------------------------------------
>
> Key: FALCON-1969
> URL: https://issues.apache.org/jira/browse/FALCON-1969
> Project: Falcon
> Issue Type: Bug
> Reporter: Ying Zheng
> Assignee: Ying Zheng
> Fix For: trunk
>
>
> Current CLI infrastructure only shows "Internal Server Error" when there is a
> server-side error. Should print error details on client side for the user to
> better understand the cause.
> See one example output from CLI and Falcon server log below. The CLI doesn't
> provide any detailed hints when the user forgets to add the required jobName
> property in the input. This information can only be found in Falcon server
> log. We should provide the hint "Missing extension property: jobClusterName"
> on CLI as well.
> CLI output:
> {code}
> [hrt_qa@os-r6-kvphku-falcon-multicluster-15 falcon]$ falcon extension -submit
> -extensionName hdfs-mirroring -file hdfs-mirroring.properties
