  • According to this github issue, create a homedir for the elastic search user github.com/elastic/elasticsearch/issues/18272 – Grayson Kent Jun 15 '17 at 19:14
  • @GraysonKent Thank you! I have a /home/elasticsearch dir, owned by user elasticsearch, and the problem persists. The error does not refer to the home dir, so not sure that home dir is the direction of the issue? – Jonesome Reinstate Monica Jun 15 '17 at 20:10

Solved this one.

/tmp was mounted noexec.

Updated /etc/fstab to mount /tmp w exec, and this issue is resolved.

Partly discussed here https://github.com/elastic/elasticsearch/issues/18406
