Briefly, this error occurs when Elasticsearch is unable to link to the C library’s native methods, resulting in the disabling of privset. This is often due to an issue with the system’s library path or an incompatible version of the library. To resolve this, you can try updating your system’s library path to include the location of the C library. Alternatively, you may need to update or downgrade the version of the C library to one that is compatible with your version of Elasticsearch.
