Gunther Hagleitner commented on HIVE-10647:
-------------------------------------------
[~vikram.dixit]:
* I think you should replace the BlockingArray<Boolean> with a counting
semaphore.
* The default for this value seems to be 1 - I think it should be
unrestricted by default.
* Since there's only one call to getLlapMode to TezWork you could just make
this call cycle through basework instead of adding another bool to the class.
If you really prefer the bool, I think TezWork should support the methods
setLlapMode/clearLlap mode w/o params (since it's not a straight forward yay or
nay).
