    When I run the command $TEZ_HOME/sbin/tez-daemon.sh start ampoolservice, I get the following error. Not sure where we need to update “0.0.0.0:8032″. Please help!

    Hi Shyamala,

    Have you made sure that the firewall (iptables) is turned off? Short of this we are looking into this issue and will get back when we have something definitive.

    Thanks,
    Ted.
