             Summary: Error is thrown by JobStats.getOutputSize() when storing to a MySql table
                 Key: PIG-4457
                 URL: https://issues.apache.org/jira/browse/PIG-4457
             Project: Pig
          Issue Type: Bug
            Reporter: Kunal Kumar


Here is an example of stack trace printed to console output. Actually, this is a warning message and does not make the job fail. The data is getting stored to mysql table, but i have no idea why pig is looking to store output on hdfs. I am using PIg along with Tez.

using output size reader: org.apache.pig.backend.hadoop.executionengine.mapReduceLayer.FileBasedOutputSizeReader
unable to find the output file
java.io.FileNotFoundException: File hdfs://pts0021.persistent.co.in:9000/user/shareinsights/filtered_stock_data does not exist.
