[jira] [Updated] (HIVE-10186) Hive does not log Tez diagnostics on errors

["Gunther Hagleitner (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HIVE-10186?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Gunther Hagleitner updated HIVE-10186:
--------------------------------------
    Attachment: HIVE-10186.1.patch

I believe patch 1 fixes this. There's already a method to pass exceptions through to the driver (which will print them with the code.). So, in this patch we concatenate the diagnostic messages from tez and add them as a "HiveException" to the Task.

> On an error, there is only a cryptic message such as: 
> "ERROR ql.Driver: FAILED: Execution Error, return code 2 from org.apache.hadoop.hive.ql.exec.tez.TezTask" 
> Tez's DAGClient reports diagnostics which would provide more information to the user
