Description

e2e test IOErrors_1 sometimes fail with

2016-10-31 17:47:25,307 [main] ERROR org.apache.pig.tools.grunt.GruntParser - ERROR 2055: Received Error while processing the map plan: Error while reading from POStream and passing it to the streaming process:Output/Error thread failed with: java.io.IOException: Index: 0, Size: 0
