Yes, this issues seems to be HDFS namenode was not stopped. Can you check
the running process by running “ps –eafww | grep proc_namenode” and if it is
running you have to stop it and start it again.
Regarding the chown error, it seems the scripts assumes the user to be
“hdfs”. Can you manually update enable-hdfs-plugin.sh and rerun it?
Line number 89 of enable-hdfs-plugin.sh
#CFG_OWNER_INF="${HCOMPONENT_NAME}:${HCOMPONENT_NAME}”
CFG_OWNER_INF=hduser
And run ./enable-hdfs-plugin.sh again?
Thanks
Bosco
