Yu Li commented on HBASE-15537:
-------------------------------
bq. If we have an existing WAL pipeline, can we pass the DN participants as
excluded when NN goes to make up the next pipeline?
We could pass in some favored nodes when creating output stream, but
unfortunately there's no API for excluding nodes... maybe we could give it a
try to see how the auto load-balance works before trying to get full control?
> Add multi WAL support for AsyncFSWAL
