Subject [jira] Updated: (HIVE-2039) remove hadoop version check from hive cli shell script
Date Thu, 10 Mar 2011 00:29:00 GMT

     [ https://issues.apache.org/jira/browse/HIVE-2039?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Joydeep Sen Sarma updated HIVE-2039:
------------------------------------

    Fix Version/s: 0.8.0
     Release Note: hive startup shell script allows bypassing running 'hadoop version' subcommand
via setting of HADOOP_VERSION environment variable. this can reduce latency of starting up
the hive cli.
           Status: Patch Available  (was: Reopened)

> looking at cli startup times - one thing i noticed is that the version check in execHiveCmd.sh
consumes 0.5-1s of wall-clock time (depending on where hive is installed).
> AFAIK - hive doesn't support versions less than 20 right now - and this check is only
to check if version is less than 20. So we should be able to safely take it out. please comment
if that is not the case.
