stack updated HBASE-20708:
--------------------------
Description:
In HBASE-20700, we make RecoverMetaProcedure use a special lock which is only
used by RMP to avoid dead lock with MoveRegionProcedure. But we will always
schedule a RMP when master starting up, so we still need to make sure that
there is no race between this RMP and other RMPs and SCPs scheduled before the
master restarts.
Please see [#[accompanying design document
|https://docs.google.com/document/d/1_872oHzrhJq4ck7f6zmp1J--zMhsIFvXSZyX1Mxg5MA/edit#heading=h.xy1z4alsq7uy]
]where we call out the problem being addressed by this issue in more detail
and in which we describe our new approach to Master startup.
