On some Linux distributions tmpfiles.d cleans files and directories under /tmp if they haven't been accessed for 10 days. This can cause problems for ML as ML is currently the only component that uses the temp directory more than a few seconds after startup. If you didn't open an ML job for 10 days and then tried to open one then the temp directory would have been deleted. This commit prevents the problem occurring in the case of Elasticsearch being managed by systemd, as systemd private temp directories are not subject to periodic cleanup (by default). Additionally there are now some docs to warn people about the risk and suggest a manual mitigation for .tar.gz users. |
