> Hi ,
> Yesterday, i run a hive on mr task,it hangs for over nine hours,after rerun
> it with the same data on the same hiveserver,the task finished in 10 mins in
> time,i am already crazy on it.
> here is the last logs for the first try(which hangs for hours):
> !image-2019-12-31-16-31-40-304.png!
>
> here is the second try(which finishs in 10 mins,the local part cost 7 seconds
> also) :
> !image-2019-12-31-16-30-55-652.png!
>
> the most weird thing is the plan.xml is different,the plans and jstack
> infomation are as attached.the cpu and memory is normal,while the process is
> so slow.

> My headache is:
> 1.Do the plan.xml can be different for the same hql and the same hiveserver
> 2.The first try runs quite slow,every records operation(put into hashmap)
> cost almost 1000ms.while the second try runs quite fast(same data and same
> hiveserver).
> Do Anyone has already met similar issues, any points will be appreciated.
> Thanks.
