Anatoli Shein commented on HDFS-11520:
--------------------------------------

Thanks for the review [~James C],

In the new (checkpoint) patch I fixed the outdated/confusing comments, added 
another place for cancellation (during OnSendCompleted), added functionality 
for adding multiple requests to the same cancel handle (for recursive stuff). 
Still working on adding more tests and support for cancellation during 
recursion/retry/failover.

> RPC calls done by FileSystem methods like Mkdirs, GetFileInfo etc should be 
> individually cancelable without impacting other pending RPC calls.
