Description

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:

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.
