Mingliang Liu commented on HBASE-20856:
---------------------------------------
In test, {{conf}} is static, which makes the newly added tests problematic as
they seem to assume clean conf object.
Another suggestion is to use different providers in {{testOnlySetWALProvider}}
and {{testOnlySetMetaWALProvider}}.
> PITA having to set WAL provider in two places

> Courtesy of [~elserj], I learn that changing WAL we need to set two places...
> both hbase.wal.meta_provider and hbase.wal.provider. Operator should only
> have to set it in one place; hbase.wal.meta_provider should pick up general
> setting unless hbase.wal.meta_provider is explicitly set.
