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

             Summary: mapreduce.client.submit.file.replication is not honored 
in cached files
                 Key: PIG-4074
                 URL: https://issues.apache.org/jira/browse/PIG-4074
             Project: Pig
          Issue Type: Bug
          Components: impl
            Reporter: Cheolsoo Park
            Assignee: Cheolsoo Park
             Fix For: 0.14.0


Pig ships files to hdfs in several cases (e.g. replicated join, streaming 
cached files, etc). But {{mapreduce.client.submit.file.replication}} (or 
{{mapred.submit.replication}} for Hadoop 1.x) is not honored, and this has 
performance impact since many tasks read the same hdfs blocks in a large 
cluster.
