Don't rely on fs.getDefaultReplication() to roll HLogs

                 Key: HBASE-2382
                 URL: https://issues.apache.org/jira/browse/HBASE-2382
             Project: Hadoop HBase
          Issue Type: Improvement
            Reporter: Jean-Daniel Cryans
            Assignee: Nicolas Spiegelberg
             Fix For: 0.20.4, 0.21.0

As I was commenting in HBASE-2234, using fs.getDefaultReplication() to roll HLogs if they
lose replicas isn't reliable since that value is client-side and unless HBase is configured
with it or has Hadoop's configurations on its classpath, it will do the wrong thing.

Dhruba added:

bq. Can we use <hlogpath>.getFiletatus().getReplication() instead of fs.getDefaltReplication()?
This will will ensure that we look at the repl factor of the precise file we are interested
in, rather than what the system-wide default value is.
