Subject [jira] [Commented] (HBASE-8294) Make HBaseConfiguration a singleton class
Date Mon, 08 Apr 2013 18:57:16 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8294?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13625667#comment-13625667
] 

Elliott Clark commented on HBASE-8294:
--------------------------------------

Keeping it not a singleton allows testing to be independent much easier.  It also allows a
more fine grain control over Hconnections and allows two clients to connect to different clusters.
 

I don't think that we should make it a singleton, perhaps we should add a function to get
a shared version of the config (maybe getSingleton() )?  Then recommend that method for most
users.  This would still allow advanced users to decide how to create their own configuration

> HBaseConfiguration.create() calls a new Configuration object. Ideally, we would like
to have just one configuration object in the jvm.
