Briefly, this error occurs when Elasticsearch is unable to install a system call filter due to the unavailability of Java Native Access (JNA). This might be because JNA is not installed or not properly configured. To resolve this issue, you can either install JNA if it’s not already installed, or ensure that Elasticsearch has the necessary permissions to access JNA. Alternatively, you can disable the system call filter by setting the ‘bootstrap.system_call_filter’ to false in the Elasticsearch configuration file. However, this might expose your system to additional security risks.
