Subject [jira] Commented: (HADOOP-5670) Hadoop configurations should be read from a distributed system
Date Thu, 16 Apr 2009 18:08:14 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-5670?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12699788#action_12699788
] 

Allen Wittenauer commented on HADOOP-5670:
------------------------------------------

#1 could be done no matter what the source.  It just depends upon how smart the plug in framework
and the actual plug in is.  For example, assuming an HTTP plug in: it would just fetch two
files and do the merge just like Hadoop configures things today.

#2 should be done no matter what the source. The question is whether it should be handled
inside or outside the plug in.

The follow up to this bug is really: how do you build a registry of configs and have the client
smart enough to know which entry it needs to follow.  So that might need to be part of the
design here. :)  [For example, if I have a client machine that needs to submit jobs to two
different grids, how can it automagically pull the proper configuration information for those
two grids? ]

> Rather than distributing the hadoop configuration files to every data node, compute node,
etc, Hadoop should be able to read configuration information (dynamically!) from LDAP, ZooKeeper,
whatever.
