Discovery.zen.minimum_master_nodes and elasticsearch_config.yml

Elastic Stack Elasticsearch
9

I can confirm that setting es.discovery.zen.minimum_master_nodes on the
command line looks as if it works unlike the setting in the config file.
Thank you Brian that looks like a workable work around.

I have additionally downloaded the deb file and the binaries and libs are
identical to my repackaged version

I have added the following to my defaults section and this looks like it
works.

Grab the number of hosts

HOSTS=grep discovery.zen.ping.unicast.hosts: $CONF_FILE | grep -v "^#" | awk -F: '{print $2}' | sed -e 's/\[//' -e 's/\]//'

NHOSTS=$(echo $(echo $HOSTS | sed "s/[,]/ /g" | wc -w))

MIN_MASTERS=$((($NHOSTS / 2) + 1))

Additional Java OPTS

ES_JAVA_OPTS="-Des.max-open-files=true
-Des.discovery.zen.minimum_master_nodes=$MIN_MASTERS"

And the log.
