I am new to Hadoop and have installed hadoop 3.1.2 on Ubuntu 16.04 in standalone mode. When I try to start daemons using start-all.sh, the command says that it is starting different daemons. However, when I check with jps, there is nothing other than jps
(sparkVenv) applied@nadeem-Inspiron-5558:~$ start-all.sh
WARNING: Attempting to start all Apache Hadoop daemons as applied in 10 seconds.
