Attached map log from table export jobs run from 2 different oozie and you can see they both
use the same path.

> n a test where we are replicating one source hcatalog table to 2 target hcat tables the
table export job runs on the source cluster. Both jobs will try to create the same dir on
hdfs and based on when they run they might run into a scenario where one fails with dir already
exists exception. Thus the hcat replication jobs can fail randomly if they have multiple targets.
