HDP 3.1 installation issues and fixes

[serbanvatavu]

Hello,
Bellow you can see some issues that I have encountered on HDP 3.1.
I present my quick fixes (I don't know if this is the best approach but maybe will help someone :) )

1. Error:
   File "/var/lib/ambari-agent/cache/stack-hooks/before-ANY/scripts/shared_initialization.py", line 50, in setup_users
   groups = params.user_to_groups_dict[user],
   KeyError: u'redis'

Fix:

I have choose 'python configs.py' solution.

2. Error:
   ImportError: cannot import name format_hdp_stack_version

Fix:
In file REDIS-5.0.0/package/scripts/params.py
replace 'format_hdp_stack_version' with 'format_stack_version'

3. Error:
   File "/var/lib/ambari-agent/cache/stacks/HDP/3.1/services/REDIS-5.0.0/package/scripts/redisSlave.py", line 30, in install
   ignore_failures=True
   TypeError: new() takes at least 2 arguments (1 given)

Fix:
Remove 'username' from 'User' object creation in both redisSlave.py and redisMaster.py.
E.g.
User(params.redis_user,
gid=params.redis_group,
groups=[params.redis_group],
ignore_failures=True
)
