Colin Patrick McCabe updated HDFS-7055:
---------------------------------------
Resolution: Fixed
Target Version/s: 2.7.0 (was: 2.6.0)
Status: Resolved (was: Patch Available)
Committed. Thanks, Stack and Masatake.
I'm really looking forward to kicking the tires on this some more. Setting up
zipkin has been on my TODO for a while. What I'd really like to do is set up a
laggy node in my 4-node cluster and see if this could detect it.
> Add tracing to DFSInputStream
