> RegExLoader hangs on lines that don't match the regular expression
> ------------------------------------------------------------------
>
> Key: PIG-1449
> URL: https://issues.apache.org/jira/browse/PIG-1449
> Project: Pig
> Issue Type: Bug
> Affects Versions: 0.7.0
> Reporter: Justin Sanders
> Priority: Minor
> Attachments: PIG-1449-RegExLoaderInfiniteLoopFix.patch,
> RegExLoader.patch
>
>
> In the 0.7.0 changes to RegExLoader there was a bug introduced where the code
> will stay in the while loop if the line isn't matched. Before 0.7.0 these
> lines would be skipped if they didn't match the regular expression. The
> result is the mapper will not respond and will time out with "Task attempt_X
> failed to report status for 600 seconds. Killing!".
> Here are the steps to recreate the bug:
> Create a text file in HDFS with the following lines:
> test1
> testA
> test2
> Run the following pig script:
> REGISTER /usr/local/pig/contrib/piggybank/java/piggybank.jar;
> test = LOAD '/path/to/test.txt' using
> org.apache.pig.piggybank.storage.MyRegExLoader('(test\\d)') AS (line);
> dump test;
> Expected result:
> (test1)
> (test3)
> Actual result:
> Job fails to complete after 600 second timeout waiting on the mapper to
> complete. The mapper hangs at 33% since it can process the first line but
> gets stuck into the while loop on the second line.
