    Hi everybody.
    I’m trying to install HDP 1.2 on amazon (small instance).

    I followed the documentation, and i have installed ambari server.

    When i try to start ambari everything seems ok.
    this is the message log:

    Using python /usr/bin/python2.6
    Starting ambari-server
    Checking iptables…
    iptables is disabled now
    Running server: /usr/jdk64/jdk1.6.0_31/bin/java -server -XX:NewRatio=2 -XX:+UseConcMarkSweepGC -Xms512m -Xmx2048m -cp /etc/ambari-server/conf:/usr/lib/ambari-server/*:/usr/lib/ambari-server/*:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin:/usr/lib/ambari-server/* org.apache.ambari.server.controller.AmbariServer >/var/log/ambari-server/ambari-server.out 2>&1

    if i check the ambari-server.out i find only this two lines:

    [EL Info]: 2013-03-16 15:03:31.552–ServerSession(41912610)–EclipseLink, version: Eclipse Persistence Services – 2.4.0.v20120608-r11652
    [EL Info]: connection: 2013-03-16 15:03:33.172–ServerSession(41912610)–file:/usr/lib/ambari-server/ambari-server- login successful

    if i run this command: ps -ef | grep Ambari
    i can’t find any process running

    Obviously if i try to reach ambari wizard from http://:8080 nothing happens.

    Can you help me please?
    Thank you in advance.

    Hi Rupert,

    Thanks for letting us know. You can also make sure that hostname -f returns correct FQDN name as other services might need to utilize FQDN names as well.

    I was in a similar situation today. The clues that I got were:
    Ambari administrator could not register
    ambari-agent was running on slaves
    ambari-agent.log said it couldn’t communicate back:
    INFO 2013-07-31 11:45:21,267 – Connecting to the following url https://master1:8440/cert/ca
    INFO 2013-07-31 11:45:21,295 – Failed to connect to https://master1:8440/cert/ca due to [Errno –
    it wasn’t using the fqdn even though I changed it in /etc/sysconfig/network and restarted the OS.
    discovered that the ambari-agent.ini does not refresh and didn’t have the correct fqdn
    so changed it as shown below
    [root@client1 ~]# sed -i -e ‘s/master1/master1.localdomain/’ /etc/ambari-agent/conf/ambari-agent.ini
    ambari-agent restart
    registering then worked



    Hi Rubens,

    What is it that goes wrong when you try to start these services? Do their respective logs tell you anything?



    Thank you Larry.

    I solved the problem.
    It was a stupid hostname issue that caused several ambari-server errors.

    Now i’m working on HBase, Hive, Zookeper issues.
    When i try to start those services something goes wrong.

    Hi, Rubens,

    Thanks for trying HDP.

    Can you please also check ambari-server.log?

    You can also run following command to check if there is ambari java process running:

    Another command to check if the port 8080:

    netstat -an| grep 8080

    Please let us know.



    Some additional information.

    I’m running Centos 6.2

    i don’t see any service listening on port 8080

    i started httpd on port 80 just to test the connectivity and everything goes fine with it.
