Starting in Common Mode

You only need to start OmniShuffle on storage nodes. After OmniShuffle is started, a message is displayed stating "ockd started successfully."

Select either the normal mode or Yarn mode to start.

1. On all storage nodes, check for the swap path (specified by the ock.ucache.server.swap.path configuration item in the ock.conf file). If the swap path does not exist, create it.
2. Run the following commands on all storage nodes:

   cd /home/ockadmin/opt/ock/ucache/24.0.0/linux-aarch64/sbin/
   sed -i '9i\export HCOM_CONNECTION_RECV_TIMEOUT_SEC=30' ock-start-ockd.sh
   source ~/.bashrc
   sh ock-start-ockd.sh
