Andor Molnar commented on ZOOKEEPER-1441:
-----------------------------------------
"it can't guarantee atomicity between the time of allocation of a port and the
time of actually binding the port inside a ZK server"
How is that possible? If all tests are using PortAssigment (which I believe is
the case), they should get different numbers, because PortAssigment maintains
that. I never actually got why PortAssigment tries to bind the port before
returns, because technically other test should not get the same number. Though
there could be other processes running on the same server which binds that
port, so it does make sense actually.
> Some test cases are failing because Port bind issue.
