---------------------------------------
Hi [~tomharrisonjr],
Please be aware that there is an improvement JIRA being in progress
(SQOOP-3216) to support other databases as Sqoop Metastore. First patch is
already available, please kindly take a look and share your thoughts on the
Review Board if you think anything is missing.
Thank you,

> Support for Mysql Sqoop Metastore
> ---------------------------------
>
> Key: SQOOP-2056
> URL: https://issues.apache.org/jira/browse/SQOOP-2056
> Project: Sqoop
> Issue Type: New Feature
> Affects Versions: 1.4.5
> Reporter: Karthic Hariharan
> Attachments: sqoop-patch.txt

>
> We would love to see sqoop metastore supported for Mysql.
> At the moment sqoop metastore can be set up only with HSQLdb. Even though you
> can fake a mysql database to look like a HSQLdb (refer
> http://bit.ly/1tz2J5u), it does not translate to compatibility to all of
> sqoop's features.
> Some of the incompatibilities are:
> * Metastore client assumes all connections to the metastore is in
> serializable transaction isolation so when sqoop job is executed it never
> really finishes because it's trying to run a transaction within a transaction.
> * Incremental loads using last modified timestamp doesnt work because the
> sqoop job tries to get the current time on the database which is a different
> sql command for Hsqldb and mysql.
