Subject [jira] [Updated] (HBASE-4815) Disable online altering by default, create a config for it
Date Fri, 18 Nov 2011 17:38:51 GMT

     [ https://issues.apache.org/jira/browse/HBASE-4815?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Ted Yu updated HBASE-4815:
--------------------------

    Description: 
There's a whole class of bugs that we've been revealing from trying out online altering in
conjunction with other operations like splitting. HBASE-4729, HBASE-4794, and HBASE-4814 are
examples.

It's not so much that the online altering code is buggy, but that it wasn't tested in an environment
that permits splitting.

I think we should mark online altering as experimental in 0.92 and add a config to enable
it (so it would be disabled by default, requiring people to enable for altering table schema).
