Ambari requires packages like nc, redhat-lsb, psmisc

[#1]

Hi,

I am installing Ambari on my server (Oracle Linux 7.2) and I've got couple of issues. In the last step I can't install services, because of errors listed below. Hadoop repo needs packages like nc, redhat-lsb or psmisc. The most strange thing is that on the other cluster where Ambari was installed I can't find packages like that. So why installation package requires them now?

How can I solve this problem? Is it about proxy or OS?

  File "/usr/lib/python2.6/site-packages/resource_management/core/shell.py", line 291, in _call
    raise Fail(err_msg)
resource_management.core.exceptions.Fail: Execution of '/usr/bin/yum -d 0 -e 0 -y install 'hadoop_2_4_*-yarn'' returned 1. Error: Package: hadoop_2_4_0_0_169-2.7.1.2.4.0.0-169.el6.x86_64 (HDP-2.4)

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

Is the other cluster on same OS level? Did you try installing these packages from RHEL repo? Try getting them installed manually, most likely you need to enable a repo and then price with install

[#3]

Can you try running 'yum update -y' on the host and retry the service install?

I enabled a repos and installed all of packages manually.

Thanks for your help.

I am getting a similar error

resource_management.core.exceptions.ExecutionFailed: Execution of '/usr/bin/yum -d 0 -e 0 -y install accumulo_2_6_0_3_8' returned 1. Error: Package: hadoop_2_6_0_3_8-2.7.3.2.6.0.3-8.x86_64 (HDP-2.6-repo-5)
           Requires: nc


which repo did you enable exactly?

[#6]

You should log in to your machine as a root user and install nc package. I don't know which OS you are using, but if it is CentOS you should execute this command (on every host machine):

yum install nc

thanks, had to adjust my repo and yum install nc worked just fine.

much appreciated
