Dmitriy V. Ryaboy commented on PIG-760:
---------------------------------------
The core test failure is in junit.framework -- doesn't seem related. Can
someone confirm this is just Hudson acting out? Here's the error report:
http://hudson.zones.apache.org/hudson/job/Pig-Patch-h8.grid.sp2.yahoo.net/109/testReport/junit.framework/TestSuite$1/warning/
The javadoc fix is trivial, holding off uploading a patch in case I need to do
something about the junit test failure.

> I'm finding PigStorage() really convenient for storage and data interchange
> because it compresses well and imports into Excel and other analysis
> environments well.
> However, it is a pain when it comes to maintenance because the columns are in
> fixed locations and I'd like to add columns in some cases.
> It would be great if load PigStorage() could read a default schema from a
> .schema file stored with the data and if store PigStorage() could store a
> .schema file with the data.
> I have tested this out and both Hadoop HDFS and Pig in -exectype local mode
> will ignore a file called .schema in a directory of part files.
> So, for example, if I have a chain of Pig scripts I execute such as:
> A = load 'data-1' using PigStorage() as ( a: int , b: int );
> store A into 'data-2' using PigStorage();
> B = load 'data-2' using PigStorage();
> describe B;
> describe B should output something like { a: int, b: int }
