Sameer Paranjpye updated HADOOP-466:
------------------------------------
Component/s: conf
> Startup scripts will not start instances of Hadoop daemons w/different
> configs w/o setting separate PID directories
> -------------------------------------------------------------------------------------------------------------------
>
> Key: HADOOP-466
> URL: http://issues.apache.org/jira/browse/HADOOP-466
> Project: Hadoop
> Issue Type: Improvement
> Components: conf
> Affects Versions: 0.5.0
> Reporter: Vetle Roeim
> Attachments: hadoop-466.diff
>
>
> Configuration directories can be specified by either setting HADOOP_CONF_DIR
> or using the --config command line option. However, the hadoop-daemon.sh
> script will not start the daemons unless the PID directory is separate for
> each configuration.
> The issue is that the code for generating PID filenames is not dependent on
> the configuration directory. While the PID directory can be changed in
> hadoop-env.sh, it seems a little unnecessary to have this restriction.
