[jira] [Resolved] (HIVE-3730) Include the metastore hostname when a connection to metastore fails due to Acces Denied

["Ashutosh Chauhan (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HIVE-3730?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Ashutosh Chauhan resolved HIVE-3730.
------------------------------------

    Resolution: Invalid

<client_hostname> is the mysql host on which access is denied. Further, this exception and thus the corresponding error message is thrown from datanucleus which cannot be modified easily.

> The current error message (from a mysql metastore) looks like {{Access denied for user 'hive'@'<client_hostname>'}}. This doesn't include the actual metastore hostname which makes it a bit harder to debug. It would be nice if this error message looked something like: {{Access denied for user 'hive'@'<client_hostname>' connecting to <metastore_hostname>}}
> Example error:
> {code}
>  javax.jdo.JDOFatalDataStoreException: Access denied for user 'hive'@'client_hostname' (using password: YES)
