-----------------------------------

             Summary: YARN localizer has to validate the mapreduce.tar.gz present in cache
before using it
                 Key: YARN-6810
                 URL: https://issues.apache.org/jira/browse/YARN-6810
             Project: Hadoop YARN
          Issue Type: Bug
          Components: nodemanager
    Affects Versions: 2.7.3
            Reporter: Prabhu Joseph


When a localized mapreduce.tar.gz is corrupt and zero bytes, all MapReduce jobs fails on the
cluster with "Error: Could not find or load main class org.apache.hadoop.mapreduce.v2.app.MRAppMaster
" as it uses corrupt mapreduce.tar.gz. YARN Localizer has to check if the existing mapreduce.tar.gz
is a valid file before using it.
