Description

Reported by Hairong. We had an HDFS error on our test cluster. It was hard to debug the HDFS NameNode logs because there was no way to map DFClient => RegionServer. Hadoop guys added a hacky config value, "mapred.task.id", which allows you to add a suffix to the DFSClient ID for logging. We should piggyback upon that for our HLog/HFile code
