> For example, when WALPlayer runs, it emits this:
> {code:java}

> mapred.Task: Final Counters for attempt_local1916643172_0001_m_000000_0:
> Counters: 20
> File System Counters
> FILE: Number of bytes read=268891453
> FILE: Number of bytes written=1018719
> FILE: Number of read operations=0

> Change it so it does this:
