Name DFSClient for Improved Debugging
-------------------------------------
Key: HBASE-2862
URL: https://issues.apache.org/jira/browse/HBASE-2862
Project: HBase
Issue Type: Improvement
Components: master, regionserver
Reporter: Nicolas Spiegelberg
Assignee: Nicolas Spiegelberg
Priority: Trivial
Fix For: 0.90.0
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
