>          Issue Type: Bug
>            Reporter: Ted Yu
>            Assignee: Ted Yu
>            Priority: Minor

> ExportSnapshot performs the following validation check before starting export:
> {code}
>     // Check if the snapshot already in-progress
>     if (outputFs.exists(snapshotTmpDir)) {
>       System.err.println("A snapshot with the same name '" + snapshotName + 
> "' is in-progress");
>       return 1;
>     }
> {code}
> The intention was to prevent concurrent snapshot export when snapshot with 
> the same name may be outstanding.
> Here is sample output:
> {code}
> hbase@ip-10-165-36-226 root$ hbase 
> org.apache.hadoop.hbase.snapshot.ExportSnapshot -snapshot snapone -copy-to 
> hdfs://10.12.113.22:8020/apps/hbase/data -mappers 1
> A snapshot with the same name 'snapone' is in-progress
> {code}
> We should note the actual path in the error message so that user can check 
> whether the snapshot with same name is still pending.
