Modifying the permission on the /opt/patch_install directory
- Log in to the Master1 and Master2 nodes as user root.
- Check whether the permission on the /opt/Bigdata/tmp directory of the Master1 and Master2 nodes is modified. (The default permission is 770.)
- If the permission is modified, run the following command to restore the permission on the /opt/Bigdata/tmp directory:
chmod 1770 /opt/Bigdata/tmp
- Log in to the active OMS node and run the following command to restart the node:
sh ${BIGDATA_HOME}/om-server/om/sbin/restart-oms.sh
The command is run successfully if the following information is displayed:
