Accessing Web Application
This is at
http://dhcp-nebula-129-210/cgi-bin/querybuilder.pl. We hope to move this to http://www-iepm.slac.stanford.edu/cgi-wrap/querybuilder.pl
Page looks like
I.e. very similar to pingtable.pl. Make your choices, for example
The above query responds with:
Accessing Hue application
http://dhcp-nebula-129-210:8888/
User name pinger, password in iepm escrow
This enables one to look at the tables created (lh column), to enter queries, and to see recent queries.
For example choose Query Editor and then Impala. Can choose metrics to chart.
May be useful to use web application to create the SQL then copy to Hue to get chart.
Accessing Cloudera Manager
http://dhcp-nebula-129-210:7180/cmf/home
User name pinger, password in iepm escrow
To look at activity of IO, network, CPU performance etc. Can also control the servers.
If you see a red in the circle for service on the left, try going to manager (at the top) , click on the down arrow for the service and Restart.
If have problems with querybuilder, it is running under Apache so will need to restart Apache. To do this ssh dhcp-nebula-129-210
sudo /sbin/service httpd [stop | start | restart]
