Subject [jira] [Commented] (HBASE-8372) Provide mutability to CompoundConfiguration
Date Tue, 23 Apr 2013 13:37:22 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8372?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13639051#comment-13639051
] 

Ted Yu commented on HBASE-8372:
-------------------------------

In a long running cluster, we should anticipate mixture of calls to set() and addXXX(). We
should support them.

If UnsupportedOperationException is thrown, code utilizing CompoundConfiguration wouldn't
be able to recover.

> In discussion of HBASE-8347, it was proposed that CompoundConfiguration should support
mutability.
> This can be done by consolidating ImmutableConfigMap's on first modification to CompoundConfiguration.
