Subject [jira] [Commented] (HBASE-7904) Make mapreduce jobs pass based on 2.0.4-alpha
Date Fri, 29 Mar 2013 20:23:16 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7904?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13617686#comment-13617686
] 

stack commented on HBASE-7904:
------------------------------

bq. I would have to go into recent checkins in more detail. This may be answered by a YARN
developer.

I suppose I could go look myself but I ask because supposedly there was an incompatibility
issue.  If tests are now passing, is it because the snapshot has incompatibilities fixed now?
 (I suppose I could look for myself but you are supposed to know what is going on here since
you are 'fixing' it).  Or is it just this config. manipulation that was needed and there is
no compatibility problem. 

Would think we would want to answer the above before we had confidence in the commit.

bq. I don't see reference to HBaseConfiguration in TestImportExport. The patch doesn't introduce
HBaseConfiguration either.

UTIL.getConfiguration is an HBaseConfiguration.

bq. cluster is a MiniHBaseCluster instance. UTIL is an HBaseTestingUtility where we store
all yarn-related conf parameters.

Where do you think cluster gets its config from?  Isn't it using UTIL.getConfiguration?

I was asking questions about the config juggling because to me it looked like the test was
doing a bunch of config copying to no useful end; that a little thought might make it so there
was less juggling going on.  Would help the developer who comes along after trying to make
sense of this test.
