Remove HDF mpack

[#1]

I am in the process of deploying my first HDP, and HDF combined cluster. I installed HDP 2.6.5 in a 5 nodes environment, and trying to install HDF mpack on top of it.

However, I accidentally installed wrong version of the HDF mpack, and wondering if there is a way I can remove it and re-install the correct HDF mpack.

Thanks in advance!

@Paul Lam I ran into the same issue in the past. Basically you will need to stop the Amberi server, then use a hidden command to remove the mpack, then reinstall the proper HDF mpack.

Here are the steps I took to get it resolved:

step1: ambari-server stop

step2: ambari-server uninstall-mpack --mpack-name=hdf-ambari-mpack --verbose

step3: ambari-server install-mpack --mpack=hdf-ambari-mpack-<version>.tar.gz --verbose

step4: ambari-server start

Please accept the answer if it helped. Thanks.

I follow those four steps, and it worked. Thanks again.

@Aaki_08 

You may want to try executing following commands:
1. On the Ambari server host:

ambari-server stop

2. On all hosts

ambari-agent stop

 3. On Ambari server host:

ambari-server uninstall-mpack --mpack-name=hdf-ambari-mpack --verbose

Hope this helps you,

Matt
