Subject [jira] [Commented] (HIVE-11707) Implement "dump metastore"
Date Tue, 01 Sep 2015 14:51:45 GMT


Alan Gates commented on HIVE-11707:

Is your goal to build something that will save the state to disk somewhere or just to transfer
the contents?  In HBaseImport (see hbase-metastore branch) we've built something that can
move data from one metastore instance to another.  This implementation is HBase specific but
that would be easy to change.  It never stores anything on disk though.

> In projects, we've frequently met the need of copying existing metastore to other database
(for other version of hive or other engines like impala, tajo, spark, etc.). RDBs support
dumping data of metastore into series of SQLs but it's needed to be translated before apply
if we uses different RDB which is time counsuming, error-prone work.
