What is best way to start and stop hadoop ecosystem, with command line?

[chintu321]

I see there are several ways we can start hadoop ecosystem,

1. start-all.sh & stop-all.sh Which say it's deprecated use start-dfs.sh & start-yarn.sh.

2. start-dfs.sh, stop-dfs.sh and start-yarn.sh, stop-yarn.sh

3. hadoop-daemon.sh namenode/datanode and yarn-deamon.sh resourcemanager

 I think there has to be some specific use cases for each command.
