---------------------------------
Resolution: Duplicate
> Hadoop ignores old-style config options for enabling compressed output when passed on from PIG
> ----------------------------------------------------------------------------------------------
>
> Key: HADOOP-8021
> URL: https://issues.apache.org/jira/browse/HADOOP-8021
> Project: Hadoop Common
> Issue Type: Bug
> Components: conf
> Affects Versions: 0.23.1
> Reporter: Anupam Seth
> Assignee: Anupam Seth
> Fix For: 0.23.1
>
>
> Hadoop seems to ignore the config options even though they are printed as deprecation warnings in the log: mapred.output.compress and
> mapred.output.compression.codec
> - settings that work on 0.20 but not on 0.23
> mapred.output.compress=true
> mapred.output.compression.codec=org.apache.hadoop.io.compress.BZip2Codec
> - settings that work on 0.23
> mapreduce.output.fileoutputformat.compress=true
> mapreduce.output.fileoutputformat.compress.codec=org.apache.hadoop.io.compress.BZip2Codec
> This breaks backwards compatibility and causes existing jobs to fail.
> This is different from HADOOP-7993 in that that one fixes any jobs run from the CLI but PIG jobs are still facing this issue.
