Guanghao Zhang commented on HBASE-23634:
----------------------------------------

[~Bo Cui]  Thanks for your suggsetion. So the new idea is not to load the 
recovered hfiles when open region and "read request" read the recovered hfiles 
directly. Meanwhile, submit a compaction request to compact all the recovered 
hfiles. The compaction result will write to the new hfile in CF dir. The 
benefits are no need many NN rpc anymore and better MTTR.

Furthermore, how about write the recovered hfile to CF dir directly? We can use 
the hfile name to distinguish which one is recovered.

> Enable "Split WAL to HFile" by default
