Wangda Tan updated YARN-3764:
-----------------------------
Description:
Currently CapacityScheduler doesn't handle the case well, for example:
A queue structure:
{code}
root
|
a (100)
/ \
x y
(50) (50)
{code}
And reinitialize using following structure:
{code}
root
/ \
(50)a x (50)
|
y
(100)
{code}
The actual queue structure after reinitialize is:
{code}
root
/ \
a (50) x (50)
/ \
x y
(50) (100)
{code}
We should forbid admin doing that.
