Infra Solr can not start after installation on Ambari 2.7.1

[#1]

Hello,

I'm trying to install Infra Solr from Ambari. After installation, when i restart the Infra Solr, the status of the service is red and it gives error below:

Traceback (most recent call last):
  File "/usr/lib/ambari-agent/lib/resource_management/core/providers/system.py", line 51, in _ensure_metadata
    _user_entity = pwd.getpwnam(user)
KeyError: 'getpwnam(): name not found: infra-solr'

The above exception was the cause of the following exception:

Traceback (most recent call last):
  File "/var/lib/ambari-agent/cache/common-services/AMBARI_INFRA_SOLR/0.1.0/package/scripts/infra_solr.py", line 171, in <module>

    raise Fail("User '{0}' doesn't exist".format(user))
resource_management.core.exceptions.Fail: User 'infra-solr' doesn't exist

I google it, but i cannot find any solution. Does anybody know the cause of this error?

I resolve the problem. The cause of the error is that when Solr is installed, Solr user and group can not be created automatically. I add Solar user and its group manually from the terminal with this command (1004 is the Oozie's group id):

useradd -g 1004 infra-solr -m -d /home/infra-solr --shell /bin/bash
