Hi, Guys

 

 I have installed cloudera 5.5 on my machine. My RAM is 8 GB. Post installing and on starting cloudera getting error "Unable to issue query: could not conect to the host monitor" on home screen. "Cluster disk", "Cluster Disk I/O" and 

"Cluster Network I/O" shows query error. i started service manually by command "$ for x in 'cd/etc/init.d ; ls hadoop-*' ; do sudo service $x stop ; done" . Still getting same error, refer screenshot attachedCloudera_Screenshot.png
