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}
> Hivemetastore add partitions can be slow depending on filesystems
