have installed Cloudera CDH 6, and then I want to install
flink using package from flink website, and run it "flink on
have down the following steps: 1. edit /etc/profile
./yarn-session.sh -n 4 -jm 2048 -tm 2048 -s 3 -nm
FlinkOnYarnSession -d -st
it always shows：
number of virtual cores per node were configured with 4 but
Yarn only has -1 virtual cores available. Please note that
the number of virtual cores is set to the number of task
slots by default unless configured in the Flink config with
is a new cluster and there is no job running, and I see in
yarn webUI there is 20 vcores available.
after I tried to add yarn.containers.vcores in
flink-conf.yml, say I add a line yarn.containers.vcores: 8,
when I run the yarn-session command, it will throw an error
"The number of virtual cores per node were configured with 8
but Yarn only has -1 virtual cores available.".
help with this problem. Thank you very much!
