Hortonworks sandbox 2.4 I can not find out how to restart service like
Ambari. So what I need to know how to restart
hadoop services from
In sandbox 2.4 the default username and password marie_dev have a read permission
for that you need to reset the username and password for admin , you can do that by lancing the script
after that you can login to Ambari by the username and password you just entered ,and there you have you admin permission :)
Log into Ambari as the administrator and from the top menu select Services->HDFS. Then navigate to the right side of the page and you will see a pulldown menu for "Service Actions". The list of available actions for HDFS will be shown in the list. You can perform a Start, Restart, Stop, etc. from this menu. I have uploaded a couple of screen shots showing the actions.
This post provides info on resetting the admin password and also provides some background on the decision.
Or you can start/stop (not restart) the service on hosts->sandbox.hortonworks.com->service you want restart (in case of hbase: hbase master and regionserver)
