Kunal Kumar created PIG-4457:
--------------------------------
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.
