Subject [jira] [Commented] (HIVE-9606) Need a tool to export metadata from RDBMS based metastore into HBase
Date Fri, 13 Feb 2015 02:44:11 GMT

    [ https://issues.apache.org/jira/browse/HIVE-9606?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14319486#comment-14319486
] 

Thejas M Nair commented on HIVE-9606:
-------------------------------------

+1
just some minor comments - 

 # In HBaseImport.java can you add a comment in run() saying that sequence of calls of the
functions is important as subsequent calls make use of information from previous calls. Alternatively,
you can change it to "copiedDbs = copyDbs(); copiedTables = copyTables(copiedDbs)" to make
it obvious.
 # hbaseConf.setVar(ConfVars.METASTORE_RAW_STORE_IMPL, HBaseStore.class.getName()); is more
concise/readable than HiveConf.setVar(hbaseConf, HiveConf.ConfVars.METASTORE_RAW_STORE_IMPL,
        HBaseStore.class.getName());
 # Do you want to create a follow up jira to track the work to migrate  index, privileges
and function metadata (I assume that is all that is left)?

> For testing (and eventually for end user use) we need a tool that can take data from
an existing RDBMS based metastore and create the corresponding objects in an HBase based metastore.
