--------------------------------------------
Hey Liang, looking at the 0.94 patch, it looks it is redoing what was done by
HBaseFileSystem and HFlogFileSystem. They already have the retrying logic. If
we this route, then we will be defining properties for retry number/wait time,
etc for all such processes.
I am working on something similar to HBASE-8211 for 0.95, and fold the hlog
rolling retry in that effort.

> A failure in log rolling causes regionserver abort. In case of HA NN, it will
> be good if there is a retry mechanism to roll the logs.
