FAQ
Hi All,

I'm new to Cloudera hadoop. I have installed and configured CDH free
edition in 2 nodes in my laptop using VMware workstation. Sometimes I'm
having hard time to connect Cloudera Manager\Admin console. It's taking
very long time to open it from my laptop browser.

Below is my situation:

After entering my CDH server host name with IP,

1) it's not opening and getting message like page not displayed, check the
name

2) After keep trying, it's prompted for credentials and taking very long
time to respond.

3) Sometimes opening without any delay

my url example: http://;192.168.XX.2:7180

Please guide on this.

Thanks and Regards,
Krishna Vuppala

    Can you check whether your VM guests are swapping? What are their
    loads? Running a full CDH + CM on two nodes, on a laptop, is a little
    unrealistic.

    If resources is a concern, I'd strongly recommend you spend a few
    dollars and run the whole thing on EC2.

    Hi Wong,

    Thanks for the below information. I have installed yesterday and I was able
    to login multiple times without any issues yesterday. This issue has been
    started from today :(.

    Will definitely give a try with EC2

    Thanks,
    Krishna

    Hi Krishna:

    Anything special in your
    "/var/log/cloudera-scm-server/cloudera-scm-server.log" file? Did you try:

    "$netstat -atnp | grep 718" on the CM server?

    and how does the /etc/hosts look like on both VM?
