      Description

      While working on BIGTOP-885, I saw that Hive was giving a bunch of warnings related to overriding final parameters in job.conf. This was on a pseudo distributed cluster. FWIW, I didn't see this happen on a fully-distributed cluster. Perhaps, Hive's job.conf is overriding some final parameters it shouldn't.

      Here is what the warnings looked like:

      2013-04-19 14:20:32,304 WARN  [main] conf.Configuration (Configuration.java:loadProperty(2032)) - file:/tmp/root/hive_2013-04-19_14-20-30_159_5701876916688815815/-local-10002/jobconf.xml:an attempt to override final parameter: mapreduce.job.end-notification.max.retry.interval;  Ignoring.
      2013-04-19 14:20:32,367 WARN  [main] conf.Configuration (Configuration.java:loadProperty(2032)) - file:/tmp/root/hive_2013-04-19_14-20-30_159_5701876916688815815/-local-10002/jobconf.xml:an attempt to override final parameter: mapreduce.job.end-notification.max.attempts;  Ignoring.
      

      To reproduce, run a query like:

      CREATE TABLE u_data (
        userid INT,
        movieid INT,
        rating INT,
        unixtime STRING)
      ROW FORMAT DELIMITED
      FIELDS TERMINATED BY '\t'
      STORED AS TEXTFILE;
      

      Load some data into u_data, here is some sample data:
      https://github.com/apache/bigtop/blob/master/bigtop-tests/test-artifacts/hive/src/main/resources/seed_data_files/ml-data/u.data

      Run a simple query on that data (on YARN/MR2)

      INSERT OVERWRITE DIRECTORY '/tmp/count'
      SELECT COUNT(1) FROM u_data
