Error when deploying services using Ambari cluster install wizard

harry_li — Sun, 18 Aug 2019 04:47:11 GMT

I am trying to setup a 2 node cluster with SPARK, HIVE using Ambari Cluster Install Wizard. I had passed first 8 steps and get stuck at "Install, Start and Test" step. Here is the error message from one of the node

I am using Ubuntu 16.04

Re: Error when deploying services using Ambari cluster install wizard

hi @Harry Li ,

Its looks like the installation is failing at step :

2018-07-2516:44:17,008-Modifying user spark

Can you investigate whether its any user creation related issue or due to some extraneous entries of users group from /etc/group

You can get the full error log from /var/lib/ambari-agent/data/error-399.json and /var/lib/ambari-agent/data/output-399.json

in the node : msl-dpe-perf74.msl.lab .

Thanks Adi and Akhil

A closer look of the issue seems pointing to failed run of hook.py, here is the message

Error: Error: Unable to run the custom hook script ['/usr/bin/python', '/var/lib/ambari-agent/cache/stacks/HDP/2.0.6/hooks/before-ANY/scripts/hook.py', 'ANY', '/var/lib/ambari-agent/data/command-399.json', '/var/lib/ambari-agent/cache/stacks/HDP/2.0.6/hooks/before-ANY', '/var/lib/ambari-agent/data/structured-out-399.json', 'INFO', '/var/lib/ambari-agent/tmp', 'PROTOCOL_TLSv1', '']Traceback (most recent call last):

I tested this script manually and here is what I got

harry.li@msl-dpe-perf74:/usr/lib/python2.6/site-packages$  sudo /usr/bin/python '/var/lib/ambari-agent/cache/stacks/HDP/2.0.6/hooks/before-ANY/scripts/hook.py'

    from resource_management import *
ImportError: No module named resource_management

I verified that my python 2.7.12 is installed correctly and resource_management directory has been installed correctly too. Is there a setting in Ambari to control python import path?

resource_management import error was caused by ambari wizard using /usr/lib/python2.6/site-packages. For Ubuntu 16, python 2.7 does not have this directory on path. It can be resolved by adding

PYTHONPATH=/usr/lib/python2.6/site-packages
