Siddharth Seth commented on HIVE-16926:
---------------------------------------
bq. Is there any action needed on this part?
I don't thing there is, unless you see this as a problem for the running spark
task. The number of threads created etc is quite small afaik.
bq. Maybe I can just replace pendingClients/registeredClients with a single
list and the RequestInfo can keep a state to show if the request is
pending/running/etc.
That'll work as well. Think there's still 2 places which have similar code
related to heartbeats - heartbeat / nodePinged.
