Subject [jira] Updated: (HIVE-1463) hive output file names are unnecessarily large
Date Mon, 19 Jul 2010 08:05:50 GMT

     [ https://issues.apache.org/jira/browse/HIVE-1463?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Joydeep Sen Sarma updated HIVE-1463:
------------------------------------

    Attachment: hive-1463.4.patch

couple of additions:
- one of the test outputs had changed because of the change in file names (sample10.q)
- TestExecDriver needs to be fixed because the tests are now picking up data/conf/hive-log4j.
switched to using mapredtask to spawn execdriver sub-process. this correctly passes system
properties down to the child process.

all tests against 17 and 20 pass.

> Hive's output files are named like this:
> attempt_201006221843_431854_r_000000_0
> out of all of this goop - only one character '0' would have sufficed. we should fix this.
This would help environments with namenode memory constraints.
