I just wanted to post this bug I ran into earlier with 5.4.0 to help other users with a workaround.
When using the tribe node ML will throw exceptions as soon as xpack is installed.
These are attached at the bottom of this post.
To solve this issue, disable ML on both the node and tribe node level like this:
tribe:
t1:
cluster.name: elasticsearch
node.ml: false
xpack.ml.enabled: false
on_conflict: prefer_t1
node.ml: false
xpack.ml.enabled: false
Future versions of xpack will have a fix so this step becomes obsolete.
