> After HBASE-20724, the compaction event marker is not used anymore when failover. So our new proposal is split WAL to HFile to imporve MTTR. It has 3 steps:
>  # Read WAL and write HFile to region’s column family’s recovered.hfiles directory.
>  # Open region.
>  # Bulkload the recovered.hfiles for every column family.
> The design doc was attathed by a google doc. Any suggestions are welcomed.
