> 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.
