Relatively new to Hive/Hadoop. For the past two days,
I haven't been able to launch Hive and it's been stuck hanging after I try to start it from PuTTy. It hangs on
WARNING: Use "yarn jar" to launch YARN applications.
Logging initialized using configuration in file:/etc/hive/2.4.0.0-169/0/hive-log4j.properties
I've tried killing all Yarn Application tasks but that doesn't work. I've tried restarting my Ambari environment. I've tried debugging at Hive Launch but it just goes on forever. Launching in MapReduce (as opposed to Tez) gets it launched, but it isn't able to perform any operators after that (e.g. create table/ select count(*)). This is what it looks like when I debug at Hive launch (it never ends!):
I'd appreciate if someone could help me out or point me in some direction! Thanks

in ambari click on hosts (upper pane of the UI) then click on the hostname, it will list you all the services along with the status.. you will find nodemanger here. click on the dropdown by selecting start.. it will start the nodemanager

@Fabienwith the ambari dashboard view it looks it's a single node cluster and your nodemanger is down, can you restart it and run the query again.

Hi Rajkumar, do you mind telling how I can restart the node/nodemanager?

@Rajkumar Singh, thanks for the guidance. I can't find the "dropdown by selecting start". I see Nodemanager, but can't find the start option. See below.
Thanks

could you please try login with the admin user instead of maria_dev.

@Rajkumar Singh user/pass: admin/admin doesn't work. I've been using maria_dev the entire time. Is there another way around this?
