Feng Peng commented on PIG-3222:
--------------------------------

Here is a sample script that can reproduce the problem:

{noformat}
register /usr/lib/hive/lib/*.jar
register /usr/lib/hcatalog/share/hcatalog/*.jar

data = LOAD 'testdata';
samples = foreach data generate 1 as number;
store samples into 'testdb.samples' using org.apache.hcatalog.pig.HCatStorer('part_dt=20130101T010000Z');
{noformat}

> Pig 0.11 assigns different UDFContextSignature for different invocations of the same load/store statement. This change breaks the HCatStorer which assumes all front-end and back-end invocations of the same store statement has the same UDFContextSignature so that it can read the previously stored information correctly.
> The related HCatalog code is in https://svn.apache.org/repos/asf/incubator/hcatalog/branches/branch-0.5/hcatalog-pig-adapter/src/main/java/org/apache/hcatalog/pig/HCatStorer.java (the setStoreLocation() function).
