Some days ago I updated my 2-node ES Cluster to 1.3.4. Since the update the
installed plugins sometimes are not applicable and for
[http://localhost:9200/\_plugin/head](http://localhost:9200/_plugin/head) returns an empty page.
This effect is seen very often after restarting a node, e.g. after SHUTDOWN
or simply killing the server process. After restart the ES cluster itself
runs an is applicable to ES java client, but none of the installed plugins
is applicable. Looks like the ES server does not deliver the plugins web
resources. When opening the index.html from head-plugin from filesystem,
the plugin runs fine.
Probably an issue with 1.3.4? My experience with earlier releases indicated
a very fault tolerant cluster, but with current release there are much
issues to plugin availablity.
Any ideas?

Anyone an idea regarding to this issue? Seems an ungraceful ES shutdown
affects the installed ES plugins ...

I've just upgraded to 1.3.4 and no problems with plugins. I upgraded
bigdesk to 2.5.0 and cloud-aws to 2.3.0 as needed for ES 1.3.4. Have you
checked you are running latest version of head?

Got it! I am using the ES java client, which becomes member of the ES
cluster. The start order is essential, when starting the client before the
server, it occupies the port 9200. There server will use the next free
port. So localhost:9200 will reach the client, which has no plugin
installed. An invalid plugin url will result in empty page.
