Upgrading plugins - probably always want to restart the cluster?

Elastic Stack Elasticsearch
1

Last week, I made some tweaks to the hunspell plugin. Specifically,
removing all the affix rules that really aren't appropriate for stemming.

Perhaps this was completely a bone-headed no-no on my part, but I overwrote
the existing plugin jar file with the new one, with the expectation that
the new plugin would get picked up when I restarted the cluster during
some upcoming maintenance.

I deleted an index which then triggered every node to crash a the same
time. Doh! If you're curious, here is the core dump:

Did I commit a cardinal sin updating the plugin jar while the cluster was
active or should this condition be handled better by elasticsearch?

Thanks!
Paul

It's not Elasticsearch related. It's a JVM bug. Just do not update jars
in the classpath while a JVM is active. See
