> Exceptions are thrown while computing splits near the end of file - typically
> when the number of bytes read is smaller than RECORD_LENGTH
> 10/08/17 22:44:17 WARN conf.Configuration: mapred.task.id is deprecated.
> Instead, use mapreduce.task.attempt.id
> 10/08/17 22:44:17 INFO input.FileInputFormat: Total input paths to process : 1
> Spent 19ms computing base-splits.
> Spent 2ms computing TeraScheduler splits.
> Computing input splits took 22ms
> Sampling 1 splits of 1
> Got an exception while reading splits java.io.EOFException: read past eof
