Subject [jira] Commented: (PIG-1680) Pig 0.8 HBaseStorage may not against HBase 0.89
Date Thu, 03 Mar 2011 05:35:36 GMT

    [ https://issues.apache.org/jira/browse/PIG-1680?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13001871#comment-13001871

Todd Lipcon commented on PIG-1680:

Hey Dmitriy,

Something strange is up with these tests - they seem to use the MiniCluster class from Pig
to start a MiniDFS and MiniMR cluster, and then they use HBaseTestingUtility.startMiniCluster
which goes and starts *another* DFS cluster. On my system (against a CDH hadoop core) this
is causing some issues where the job jar ends up on the wrong HDFS and the test fails.

>    Affects Versions: 0.8.0

>             Fix For: 0.9.0

> HBaseStorage is currently coded against the hbase 0.20.6 API. The hbase 0.89 API deprecates
some methods and outright removes some others which causes HBaseStorage to no longer compile.
> It is unclear whether one can run an HBase 0.20.6 client against a running 0.89 hbase
instance. In my experience, it does not work. Therefore, HBaseStorage has to be compiled against
> Attached is a proposed patch to make 0.8.0 trunk compatible with hbase 0.89 as well as
a script to help automate the upgrade.
