Subject [jira] [Commented] (HIVE-13901) Hivemetastore add partitions can be slow depending on filesystems
Date Wed, 01 Jun 2016 16:41:59 GMT

    [ https://issues.apache.org/jira/browse/HIVE-13901?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15310604#comment-15310604
] 

Steve Loughran commented on HIVE-13901:
---------------------------------------

Those catch and wrap exceptions need to retain the inner one as otherwise the exception cause
can never be really identified.

{code}
// from
throw new MetaException(e.getMessage());

// to
throw new MetaException(e.getMessage(), e);

// or, if that constructor isn't there
throw (MetaException)new MetaException(e.getMessage()).initCause(e);
{code}

> Depending on FS, creating external tables & adding partitions can be expensive (e.g
msck which adds all partitions).
