Public service announcement: Sqoop Metastore on other DBs may fail

We have been able to get PostgreSQL and MySQL working as targets for the Sqoop Metastore on Sqoop 1, replacing the HyperSQL database. There's a little setup and seeding of the database needed, but from then on, it seemed fine.

However, we are seeing cases when we are running many sqoop jobs, updating the metastore concurrently -- sqoop 1.4.6 has no code to trap and handle cases where metastore updates for incremental updates fail due to concurrency issues. In particular, Sqoop _will complete it's import successfully but not update the metastore with the most recently imported values. This will cause the next incremental run will import duplicate data. Sqoop will return a non-zero return code, but data in either Hadoop or the metastore need to be synced afterward in order for data to be correct.

We're not sure there is a solution, but this is an expansion of @SandeerKumar's answer. This may be an issue with HyperSQL as well, but it would be much less likely because HSQL is in memory, so faster.
