Re: sqoop2 always results in

Expert Contributor

This error is because you have configured a minimum required replication rather than a default level of replication.


Some systems, like Sqoop 2, purposefully set a low replication level for temporary files that they aren't worried about losing. With a required minimum replication the namenode will reject these requests as invalid.


The fix is to update the minimum required replication back to 1. Do this by resetting the property dfs.namenode.replication.min.
