[jira] [Updated] (PIG-2909) Add a new option for ignoring corrupted files to AvroStorage load func

["Cheolsoo Park (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/PIG-2909?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Cheolsoo Park updated PIG-2909:
-------------------------------

    Attachment: PIG-2909.patch
                PIG-2909-avro_test_files.tar.gz

Attached is a patch that adds a new option 'ignoreBadFiles' to AvroStorage load. When it's enabled, AvroStorage load func skips bad files instead of failing.

I am also attaching two test cases:
- Load a corrupted avro file with 'ignoreBadFiles'.
- Load a corrupted avro file without'ignoreBadFiles'.

> Currently, AvroStorage load fails with AvroRuntimeException when encountering corrupted input files. For example,
> {code}
> ERROR 2997: Unable to recreate exception from backed error: java.io.IOException: org.apache.avro.AvroRuntimeException: java.io.IOException: Invalid sync!
> 	at org.apache.pig.piggybank.storage.avro.AvroStorage.getNext(AvroStorage.java:283)
> {code}
> But it is not always desirable to fail the Pig job for bad files. It is sometimes more useful to skip them and continue.
