Subject [jira] Commented: (HBASE-1680) FilterList writable only works for HBaseObjectWritable defined types
Date Wed, 22 Jul 2009 23:03:14 GMT

    [ https://issues.apache.org/jira/browse/HBASE-1680?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12734369#action_12734369
] 

Jonathan Gray commented on HBASE-1680:
--------------------------------------

@Clint, don't we just need to add FilterList?

In HbaseObjectWritable:

{code}
+    addToMap(FilterList.class, code++);
{code}

> So I can't have a filter list of my own filters. (Also a filter list of filter lists
does not work because FilterList is not in HBaseObjectWritable)
