Zookeeper connection pool / fault handling for geoserver plugin

[chrisbennight]

The current geoserver plugin dies (tomcat needs to be restarted) if the zookeeper cluster goes down and is then restarted (due to persistent zookeeper connections).

Some sort of connection pooling might also need to be enabled as there's a limit to the number of simultaneous zookeeper connections we want (due to internal collection synchronization).

I was unable to recreate this issue. What follows is a list of the steps that I used to recreate the issue:

• Load a layer preview within geoserver
• Shutdown Zookeeper with Cloudera Manager and wait 5 minutes
• Startup Zookeeper
• Restart each Accumulo node
• Change the view area within the previous layer preview
  • Additionally, close and reload the layer preview tab and pan over a new area

Using this sequence of steps, I was able to get data from geoserver without a restart. I was also able to verify that there were active table scans running while I played with the layer preview.

I'll keep an eye on this one in case it pops up again in the future...
