Date Mon, 08 Jul 2013 16:39:51 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8015?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13702105#comment-13702105

Francis Liu commented on HBASE-8015:

[~saint.ack@gmail.com] I've pushed changes into github, the changes mainly addresses one thing:
make namespace as first class. I've replaced internal apis which took "byte[] tableName" as
a constant to use FullyQualifiedTableName instead. For HTable and HBaseAdmin, I've overloaded
such functions instead to keep backward compatibility. Also created a new branch in the repo
which is a rebase off trunk yesterday. I'll address your RB comments today.

Some issues:
- The external interfaces: cli, thrift, rest and MR don't have the namespace as first class
treatment yet
- I initially went by the InterfaceAudience annotations but after talking to you guys it seems
this is needs some updating as HConnection and HConnectionManager are both marked public tho
they shouldn't be?
- There are some apis (ie compact()) which have an overloaded parameter ie "byte[] tableOrRegionName"
should we be splitting this into two apis and deprecate the old one?
- Need to create a FullyQualifiedTableName PB equivalent and update PB rpc and messages as
- I always needed to add commons-io as a maven dependency else things won't compile and these
aren't related to my changes
- Ran small,med,large tests and have these failures which aren't related to the patch: TestHCM.testClusterStatus,
TestLogRolling.testCompactionRecordDoesntBlockRolling, TestShell
