This is a fork (with some Ubuntu fixes) of a fork (with ES 8.x support) of the old (no longer supported) elastic supplied ansible role for installing ES 7.x.
It has been kept in its original form in case upstream fixes become available, for transparency regarding who changed what and when, and to encourage leaving it alone (avoiding temptation to "improve" it).
It's used by mediacloud/newsscribe-ansible
NOTE!!!! Installs elasticsearch version 8.17.3, accordingly jvm.options.j2 has been updated to the version from that release. BUT files not used at Media Cloud have NOT been updated!
