Installer does not copy Elasticsearch configuration into BITBUCKET_HOME/shared/search

Summary

The installer for Linux does not copy the contents of BITBUCKET_INSTALL/elasticsearch/config-template into BITBUCKET_HOME/shared/search which results in Elasticsearch running but listening on port 9200 and not 7992 that we expect.

Environment

• Linux using the bin installer

Steps to Reproduce

Install Bitbucket Server as root on a Linux machine without the atlbitbucket user account, and select Install as a service: Yes.

Expected Results

BITBUCKET_HOME/shared/search contains the following files:

├── buckler
│   └── buckler.yml
├── elasticsearch.yml
└── logging.yml

Actual Results

BITBUCKET_HOME/shared/search does not contain the required yml files.

The <Bitbucket Installation directory>/.install4j/installation.log contains a message of the form:

[ERROR] com.install4j.runtime.installer.helper.launching.LaunchHelper: return value is 1
[INFO] com.install4j.runtime.installer.helper.launching.LaunchHelper: stdout output was empty
       
stderr output:
---BEGIN---
su: user atlbitbucket does not exist
---END---

The instance launches normally, but all code and repository search functionality doesn't work. On the Administration >> Server settings page the Search settings show a blank username and password.

Workaround

1. Copy the files from BITBUCKET_INSTALL/elasticsearch/config-template folder to BITBUCKET_HOME/shared/search 
2. Restart Elasticsearch
