-------------------------------------
@zsxwing
>> Do you have the whole jstack output?
I will not be able to share it as is .. but then looking at the entire 7k lines
of jstack file and removing stuff like ip address or any company internal stuff
seems to be lot of work to me.
>> Could you check you disk? Maybe some bad disks cause the hang.
At the time this happened, I did not notice any problems with disk on the box.
However, will keep an eye about that next time.
>> By the way, how did you use Spark? Did you just run it or call it via some
>> Process APIs?
We run spark jobs directly via spark-shell

> threads per the jstack, this is where the driver seems to be stuck.
