> 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.
