> When using the --password-file option, a Sqoop action running inside an Oozie workflow
will ERROR out at the very end, like so:

> With the --password option, the job completes with no error. I believe the --password-file
option handling closes the FS which happens to be shared with the Oozie launcher, which can't
write to it anymore on completion. The solution I found was adding:
> {noformat}
>   <property>
>     <name>fs.hdfs.impl.disable.cache</name>
>     <value>true</value>
>   </property>
> {noformat}
> in the sqoop action definition in the oozie workflow, and that works, but isn't really
handy.
