Cheolsoo Park commented on PIG-2837:
------------------------------------

@Santhosh,

Thanks for reviewing my patch!

Regarding the other test failures,

1) If I run the following commands, I don't see TestDBStorage failure in Hadoop 
20:
{code}
ant clean compile-test jar-withouthadoop -Dhadoopversion=20 // Note 
jar-withouthadoop
cd contrib/piggybank/java
ant clean test -Dtestcase=TestAvroStorage -Dhadoopversion=20
{code}

2) I believe that TestDBStorage/TestMultiStorage/TestLookupInFiles failures are 
due to some mini cluster mis-configuration:
{code}
2012-08-06 01:13:52,340 INFO  [AsyncDispatcher event handler] rmapp.RMAppImpl 
(RMAppImpl.java:transition(533)) - Application application_1344240816627_0001 
failed 1 times due to AM Container for appatt     
empt_1344240816627_0001_000001 exited with  exitCode: 127 due to:
{code}

While I see them failing on Mac, they run fine on CentOS 6. I am wondering if 
it would be better to modify these tests so that they will run in local mode 
instead of mr mode.

Thanks!

> format, data looks good.
