Subject [jira] Commented: (HBASE-62) [hbase] Allow user add arbitrary key/value pairs to table and column descriptors
Date Wed, 02 Jul 2008 11:02:45 GMT

    [ https://issues.apache.org/jira/browse/HBASE-62?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12609879#action_12609879

Andrew Purtell commented on HBASE-62:

I attached another patch that uses SortedMap instead of Map. 

For migration the proposed HTD.readFields needs an integer (written by .writeInt()) ahead
of the rest of the serialized HTD to process the old format. I have tried to make migration
easy. All that needs to be done is a simple prepend of a serialized integer to the serialized
HTDs in .META., but I don't know how migration scripts work so maybe that is not simple or
a complete rewrite is no problem...
