[jira] Updated: (HADOOP-1928) [hbase] Have master pass the regionserver the filesystem to use

["stack (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HADOOP-1928?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

stack updated HADOOP-1928:
--------------------------

    Attachment: master_passing_config.patch

Here's a first cut.  Lots of HRegionServer refactoring so no fs access nor service thread startups until after we've had our first conversation with master.  Needs testing on a cluster.

> The less configuration needed starting a regionserver the better.  Currently the regionserver needs to read hadoop-site mainly so it knows which filesystem to go against.  If it could get this info from the master instead when it gets the response to its reporting-for-duty message, then the dependency on hadoop-site.xml could mostly go away.
> Looking at regionserver, it looks like it would just take a little reorganization so that the hlog opening and the startup of worker threads doesn't happen until after we get our first response from the master.
