Subject [jira] [Commented] (HBASE-4716) Improve locking for single column family bulk load
Date Wed, 02 Nov 2011 17:33:32 GMT

    [ https://issues.apache.org/jira/browse/HBASE-4716?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13142326#comment-13142326

Todd Lipcon commented on HBASE-4716:

this was already committed, but I just got to my email for the day:
- why does getColumnFamilyType return an enum when all we care about is hasMultipleColumnFamilies()
(a boolean?) This makes it harder to understand. (this function doesn't return a type of column
- even if you use an enum, our style is not ALL_CAPS for enum class names. Only ALL_CAPS for
the values.
- why is the new function public? it should be private.
