Subject [jira] Commented: (HADOOP-466) Startup scripts will not start instances of Hadoop daemons w/different configs w/o setting separate PID directories
Date Mon, 28 Aug 2006 07:24:23 GMT
    [ http://issues.apache.org/jira/browse/HADOOP-466?page=comments#action_12430940 ] 
            
Vetle Roeim commented on HADOOP-466:
------------------------------------

Ah, I didn't know it worked like this. Seems that it might be a useful feature.

But all I want is the hashing, so does HADOOP_IDENT_STRING stay in, or should it be taken
out? Perhaps this should be another issue entirely?

> 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.
