Jarek Jarcec Cecho commented on SQOOP-2056:
-------------------------------------------
Thank you for creating the JIRA [~khariharan]! I just wanted to mention that
the community is currently more focusing on developing Sqoop 2 rather then
adding features to Sqoop 1. We already have tracking JIRA for MySQL Repository
- SQOOP-940. Having said that, patches are definitely welcome and I'll be more
then happy to do a review if you want to take a stab at this feature :)
> Support for Mysql Sqoop Metastore
> ---------------------------------
>
> Key: SQOOP-2056
> URL: https://issues.apache.org/jira/browse/SQOOP-2056
> Project: Sqoop
> Issue Type: New Feature
> Reporter: Karthic Hariharan
>
> 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.
