Hello,
How to perform a restart of single node Elasticsearch (with multiple instance in) ?
The option "index.unassigned.node\_left.delayed\_timeout" positioned at 10 minutes is sufficient ?
Here my script to reboot a single node with multiple instance :
#!/bin/ksh
hostELS=`hostname | cut -d"." -f1`
curl -X PUT "${hostELS}:9200/\_all/\_settings" -H 'Content-Type: application/json' -d'
{
"settings": {
"index.unassigned.node\_left.delayed\_timeout": "10m"
}
}
'
instances\_number=`ls /opt/application/ | grep "[0-9][0-9]"`
for i in $instances\_number
do
sh /opt/application/$i/bin/Operate.sh stop
done
What do you think ?
Options like cluster.routing.allocation.enable is useless no ?
Thanks for reply
