Olga Natkovich commented on PIG-2391:
-------------------------------------
Looks like our comments crossed. So the issue is that Hadoop does not
understand .bz extension and you need to fake it by saying it is actually bz2.
> Bzip_2 test is broken
> ---------------------
>
> Key: PIG-2391
> URL: https://issues.apache.org/jira/browse/PIG-2391
> Project: Pig
> Issue Type: Bug
> Affects Versions: 0.10
> Reporter: Olga Natkovich
> Assignee: xuting zhao
> Fix For: 0.10, 0.11
>
> Attachments: PIG-2391.patch

> This test is currently commented out but if you uncomment it it fails with
> Pig 10 but runs successfully with Pig 9.
> Script:
> a = load '/homes/olgan/studenttab10k' using PigStorage() as (name, age, gpa);
> store a into 'intermediate.bz';
> b = load 'intermediate.bz';
> store b into 'final.bz';
> A couple of observations:
> (1) Identical script (represented by Bzip_1 test) that has bz2 instead of bz
> extension in the script succeeds in Pig 10
> (2) The problem occurs while reading intermediate.bz which has different size
> with Pig 9 and Pig 10
> (3) Problem can be reproduced in local mode with small subset of data in the
> file
> (4) The following stack trace is observed:
