I see there are several ways we can start hadoop ecosystem,
-
start-all.sh & stop-all.sh Which say it’s deprecated use start-dfs.sh & start-yarn.sh.
-
start-dfs.sh, stop-dfs.sh and start-yarn.sh, stop-yarn.sh
-
hadoop-daemon.sh namenode/datanode and yarn-deamon.sh resourcemanager
I think there has to be some specific use cases for each command.
