Sorry, you’ve beat me. Mike, what have you found in full-dev? Does ES work correctly there?

Yes, I'm saving the changes. The orange bar pops up saying I have to restart elasticsearch, which I do. I'm logged in with the admin user, it has privileges to do everything else. I'm using a bare metal install via Ambari. Everything else seems to work through Ambari except this :) On 2017-09-13 12:04, Matt Foley wrote: That it doesn't work in Ambari, at least to the point of writing thru to the config file (whether or not it actually works with ES), is quite mystifying. Silly question, but, are you pressing the "Save" button after changing the field? Are you perhaps not logged into Ambari with an ambari user id that has privs to change this config? Did you use non-default user configuration with Ambari, and if so are you running with an admin-priv ambari account?

See inline. Now, Laurens, two question for you: First, please confirm: Are you setting the value of masters_also_are_datanodes via the masters_also_are_datanodes field in the Ambari configuration GUI? Or directly editing files? I'm using Ambari to edit the configuration. However, I have to manually edit the file locally as the Ambari configuration doesn't work. Second, do you set it at the initial install time, or afterward? I'm pretty sure it needs to be set at initial install time, before you ever launch the Elasticsearch nodes. I'm dubious about whether an Elasticsearch master can learn to be a datanode if it first wakes up and configures itself to not be one. But I'm not an Elasticsearch expert, so if someone else knows different, please say so. In this case, I forgot to set it initially, so I tried to change it afterwards to no avail. Hope this helps more than obfuscates. --Matt From: Michael Miklavcic <[email protected]> Date: Tuesday, September 12, 2017 at 4:54 PM To: "[email protected]" <[email protected]> Cc: Matt Foley <[email protected]> Subject: Re: Elasticsearch masters_also_are_datanodes doesn't work. At the very least, the value provided by default seems to have changed to a "1" instead of "true" without the tooltip having been updated to match. Error! Filename not specified.

It's only a 1-node VM, so I'm pretty sure that it would not work otherwise. I'm spinning up full dev now and will look into it also.

This may be a showstopper, as it presumably (?) prevents ES from working on a single-node deployment?
