Issue in running 2 applications

[Rishikesh Gawade]

Hello there.
I have been using Apache Apex for a while. Recently, i tried to launch 2
Apex applications simultaneously on a single Hadoop cluster. However, only
one of them entered the RUNNING state while the other one kept waiting in
ACCEPTED state and transited into RUNNING state as soon as the first app
was shut down. Could you please explain how to run 2 apps simultaneously?
Thanks in advance.
