[jira] [Commented] (HIVE-3819) Creating a table on Hive without Hadoop daemons running returns a misleading error

["Sean Mackrory (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-3819?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13602318#comment-13602318 ] 

Sean Mackrory commented on HIVE-3819:
-------------------------------------

I just ran into this error while Hadoop daemons were running but the problem was that the Hive Metastore was running (backed by the embedded Derby database) and the hive client was running in embedded mode and also trying to connect to the embedded Derby database. Perhaps there are multiple common misconfigurations that result in this error.

> I was running hive without running the underlying hadoop daemon's running. Hadoop was configured to run in pseudo-distributed mode. However, when I tried to create a hive table, I got this rather misleading error:
> {code}
> FAILED: Error in metadata: java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.metastore.HiveMetaStoreClient
> FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask
> {code}
> We should look into making this error message less misleading (more about hadoop daemons not running instead of metastore client not being instantiable).
