i create a new client host outside the cluster by copying directory hdp & current & /etc/<conf> of one of the cluster's host
i can submit mr jods at this host
but when i submit jobs by different user at the same time , i find out these jobs running one by one like FIFO
how to run synchronzed?
do you have enough resource available on the cluster, can you check if the other jobs submitted are in ACCEPTED stage in RM UI.
