    I installed Ambari 1.6.1 and everything worked well until I decided to shutdown my virtual machine. Before shutdown I stopped all HDFS/YARN and other Hadoop related services. After several days I started virtual machine again and found that I can’t start Hadoop related services using Ambari Web UI, because all such services in the services list were highlighted with yellow icon and there was no start button to start services.

    I also tried to do this:

    ambari-server stop
    ambari-agent stop

    ambari-server start
    ambari-agent start

    to restart Ambari services, but it didn’t help, cause I still see Heartbeat Lost message and have no button to start services.

    In ambari-agent logs I also found such messages:

    INFO 2014-08-09 09:09:18,761 NetUtil.py:81 – Server at https://<my-host&gt;:8440 is not reachable, sleeping for 10 seconds…
    INFO 2014-08-09 09:09:28,772 NetUtil.py:42 – Connecting to the following url https://<my-host&gt;:8440/cert/ca
    WARNING 2014-08-09 09:09:30,769 NetUtil.py:62 – Failed to connect to https://<my-host&gt;:8440/cert/ca due to [Errno 113] No route to host

    Can it be somehow related to the fact that IP address of the virtual machine has changed (but host name still the same) ?

    hi Igor,
    You r right it’s due to IP address of your virtual machine has changed.so just edit /etc/hosts file according to your changed ip address.
