i want to do the tutorial for sentiment Analysis. But after the first step of installing NiFi my system doesnt work correct anymore. i cant restart all the services and when i try all services got yellow and out of heartbeat. At the moment SNameNode from HDFS is stopped, HBase Master and NiFi Server also. Is it possible to start them through command line or does anyone have an idea how i get this system back to work to continue the tutorial ? iam already afraid of installing solr and need to restart again.
I can only speak to any NiF issues here, but what do you mean by "my system doesn't work correct anymore"?
If you stop NiFi, does your system go back to normal? Perhaps you do not have enough resources to run all these services on your machine.
i mean that now every time i start the sandbox hdfs hbase nifi and some other services are red. i can start nifi and hbase manually. at hdfs only the snamenode is stopped and i cant start it manually. i will just try to continue the tutorial now.
