Hadoop ignores old-style config options for enabling compressed output

      Description

      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 was found to happen due to the JobSubmitter writing out the job.xml file with the old-style configs and can be fixed by handdling deprecation before the file is written out.

          The javadoc warnings are unrelated.

          Overall the patch looks good to me, btu I do have a few comments.

          In your test, it looks like test-config.xml is never deleted. It would be better if you could use a temp file. That way you don't have to worry about collisions between files already on disk, and you don't have to worry about the file going away at the end of the test. Or even better if you could use a ByteArrayOutputStream instead of writing to a file at all.

          In Configuration.handleDeprecation() could you change all calls to LOG.info to LOG.debug or just to be comments. We don't need to it be printed out every time we write out a config file. Also it looks like all you need are the property keys. You might not need to clone the entire property object. Just call getProps().keys() or getProps().keySet().

          Just to clarify the reason for proposing the code change the way it is in the patch is that upon investigation, our understanding was that the old-style config was being written to file by the JobSubmitter before the replacement with the keys listed in MR deprecated keys are invoked, e.g. by a get. Thus, when the AppMaster tried to read in the config coupled together with mapred-default which currently has this set to false, the old-style config was being overriden to be whatever was specified in the default file. As a solution, therefore, we force handling deprecation on all keys before the job.xml gets written out.
