Thejas M Nair commented on HIVE-14129:
--------------------------------------
[~ashutoshc] It doesn't look like the 2nd issue is fixed. ie -
bq. 2. SessionState is examined by acid code in MoveTask, if it is in a
different thread that thread will not have the SessionState object available.
TaskRunner would need an additional method - setSessionState, similar to
setOperationLog, that sets the thread local sessionstate.
Also, we should check if the methods being used in MoveTask on SessionState for
acid purposes are thread safe. Looking at the method names, I would expect it
to be threadsafe. cc [~ekoifman]
Without that we might have issues with ACID and execparallel=true.
