Description

hi ,
We are facing an below error while running custom writable code, our driver code is using below code . logwritable is the name of custom writable interface.

--Error message at the code execution is as follows
DFSClient_NONMAPREDUCE_549327626_1 doesnot have any open file

--Driver code -
job.setMapOutputKeyClass(logwritable.class);
job.setMapOutputValueClass(logwritable.class);
job.setNumReducerTasks(0);

--logwritable class implements Writable interface
--Definition of mapper is as follows

public class MAPPER extends Mapper<Text,IntWritable,Logwritable, Logwritabe>{
....

}

Any help to resolve above issue will be great help
