Duo Zhang commented on HBASE-17021:
-----------------------------------
[~stack] [~ram_krish] As this patch could fix the contention and unexpected wal
roll, let's commit it first?
I will do some other changes to see if I can make AsyncFSWAL run faster for a
single node HDFS. For me, the WALPE is OK but in PE AsyncFSWAL is much slower.
Thanks.
