Duo Zhang commented on HBASE-22874:
-----------------------------------
And since you said you want to get something back, then I do not think this is
a suitable way to you as there is no way to intercept the input and output of
the Tool, unless you do some magic on the Tool it self but this will break the
assumption that you can only use the method from the Tool interface.
So I think we still need an interface here. Just like the BulkLoadHFiles.
Thanks.
