Hi friends, Im in CDH 6.2 and hence trying to check jps command through cmd prompt. Not sure why it is not showing up hadoop services on issuing it and hence returning with below error [root@cloudera bin]# jps bash: jps: command not found... Kindly help me out with this. Regards, GTA ... View more

Hi friends,   I have cloudera trail version 6.2. In the command prompt when i tried to initiate spark shell using   spark-shell, im getting the below error:   [root@cloudera tmp]# spark-shell Setting default log level to "WARN". To adjust logging level use sc.setLogLevel(newLevel). For SparkR, use setLogLevel(newLevel). 20/04/09 08:19:33 ERROR spark.SparkContext: Error initializing SparkContext. java.lang.IllegalArgumentException: Required executor memory (1024), overhead (384 MB), and PySpark memory (0 MB) is above the max threshold (1024 MB) of this cluster!

Hi friends,   I have CDH 6.2.1 setted up in my local server. I can login to cloudera manager to monitor all the components and its running status. Meanwhile im trying to found how to access Cloudera navigator and stuck with it. Can you guide me how to access the same.   Even i followed the below steps, it dint help as i couldnt locate the navigator How can I access the Cloudera Navigator console? The Cloudera Navigator console can be accessed from the Cloudera Manager Admin Console or directly on the Navigator Metadata Server instance. Using the Cloudera Manager Admin Console as a starting point requires the Cloudera Manager roles of either Navigator Administrator or Full Administrator. From the Cloudera Manager Admin Console: Select Clusters > Cluster-n. Select Cloudera Navigator from the menu. To access the Cloudera Navigator console directly: Open the browser to the host name of the node in the cluster that runs the Cloudera Navigator Metadata Server. For example, if node 2 in the cluster is running the Navigator Metadata Server role, the URL to the Cloudera Navigator console (assuming the default port of 7187) might look as follows http://fqdn-2.example.com:7187/login.html   :Log in to the Cloudera Navigator console using the credentials assigned by your administrator.
