stack commented on HBASE-18792:
-------------------------------
[~davelatham] Hopefully it'll be needed less often than in the past but yeah we
need an hbck2 (HBASE-19121). Its very vocabulary will be different because it
all works so differently now. Idea is to start a new subproject so we can roll
out improvement in it quickly.

> hbck needs updating to run against hbase2. Meantime, if an hbck from hbase1
> is run against hbck2, it may do damage. hbase2 should defend itself against
> hbck1 ops.
