[jira] [Created] (PIG-4932) Cache files not loaded when using 'limit' operator

hemanth meka created PIG-4932:
---------------------------------

             Summary: Cache files not loaded when using 'limit' operator
                 Key: PIG-4932
                 URL: https://issues.apache.org/jira/browse/PIG-4932
             Project: Pig
          Issue Type: Bug
    Affects Versions: 0.14.0
            Reporter: hemanth meka


UDF in pig throws error when input is fed to the UDF after applying LIMIT operator. The UDF is not able to find the cache file when using LIMIT

org.apache.pig.backend.executionengine.ExecException: ERROR 2078: Caught error from UDF: org.test.hadoop.pig.BagProcess [Caught exception: File './names_cache' does not exist]

By removing the LIMIT and directly feeding the input to UDF it runs fine. LIMIT operator seems to not load the cache files causing the issue. I was able to regenerate this on two different cluster running 0.14.0 version of hive
