Subject [jira] [Updated] (HIVE-11304) Migrate to Log4j2 from Log4j 1.x
Date Sat, 01 Aug 2015 02:23:04 GMT

     [ https://issues.apache.org/jira/browse/HIVE-11304?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Prasanth Jayachandran updated HIVE-11304:
-----------------------------------------
    Attachment: HIVE-11304.4.patch

Fixed test failures. The issue was with iterating over file appenders and printing file location
in qfile test. The old api for iterating over existing appenders do not work anymore. 

[~gopalv] Can you take a look at the new patch?
