v5.5.3

IMPORTANT: Upgrading from 5.5.0, 5.5.1 or 5.5.2

If you're upgrading from 5.5.0, 5.5.1 or 5.5.2, during the uninstallation of the older version that happens after installing the new version

• the service is stopped
• the ES_CONFIG and ES_HOME environment variables are unset
• plugins installed as part of the upgrade are uninstalled

To fix,

1. Set ES_CONFIG environment variable to the location of the config directory (default is C:\ProgramData\Elastic\Elasticsearch\config). For example,

   with PowerShell

   [Environment]::SetEnvironmentVariable("ES_CONFIG", "C:\ProgramData\Elastic\Elasticsearch\config", "Machine")

   or with cmd.exe

   setx ES_CONFIG "C:\ProgramData\Elastic\Elasticsearch\config" /m

2. Set ES_HOME environment variable to the location of the installation directory (default is C:\Program Files\Elastic\Elasticsearch). For example,

   with PowerShell

   [Environment]::SetEnvironmentVariable("ES_HOME", "C:\Program Files\Elastic\Elasticsearch", "Machine")

   or with cmd.exe

   setx ES_HOME "C:\Program Files\Elastic\Elasticsearch" /m

3. Reinstall plugins that you require using the following for each plugin, within the installation directory (default is C:\Program Files\Elastic\Elasticsearch). You may need to do open a new terminal, so that the new machine environment variables for ES_HOME and ES_CONFIG are picked up.

   with PowerShell

   $env:CONF_DIR = [Environment]::GetEnvironmentVariable("ES_CONFIG", "Machine")
   bin\elasticsearch-plugin.bat install plugin_name --batch

   or with cmd.exe

   setx CONF_DIR "%ES_CONFIG%"
   bin\elasticsearch-plugin.bat install plugin_name --batch

4. If you specified to install as a Windows service and to start after installation/upgrade, you can now start the service. For example,

   with PowerShell

   Start-Service Elasticsearch

   or with cmd.exe

   sc start Elasticsearch
