> One of our users reports they see intermittent failures due to attempt
> directories in the input paths. We found with speculative execution turned
> on, two mappers tried to commit task at the same time using the same
> committed task path, which cause the corrupt output directory.
> The original Pig script:
> {code}
> STORE AdvertiserDataParsedClean INTO '$DB_NAME.$ADVERTISER_META_TABLE_NAME'
> USING org.apache.hcatalog.pig.HCatStorer();
> {code}
> Two mappers
> attempt_1405021984947_5394024_m_000523_0: KILLED
> attempt_1405021984947_5394024_m_000523_1: SUCCEEDED
> attempt_1405021984947_5394024_m_000523_0 was killed right after the commit.
> As a result, it created corrupt directory as
