DistributedBeans should not close their RPC counterparts

Key: NUTCH-857
URL: https://issues.apache.org/jira/browse/NUTCH-857
Project: Nutch
Issue Type: Bug
Affects Versions: 1.1
Environment: All
Reporter: Dennis Kubes
Assignee: Dennis Kubes
Fix For: 1.2
Attachments: NUTCH-857-1-20100619.patch
DistributedSearch and Segment Beans currently call close on their RPC
counterparts from their own close methods. This results in killing (closing)
all distributed servers when the main bean (website, application, etc) is
shutdown. DistributedSearchServer (SegmentServer) are run independent from the
main NutchBean or website calling those servers in shard type environments.
With the current code the distributed servers are closed and any further search
requests throw IndexAlreadyClosed exceptions. The distributed servers have to
be restarted before searching can resume. Obviously this doesn't work in a
large distributed search where multiple beans could be called the distributed
servers and where distributed servers could be coming up and down frequently.
The solution is simple though. The Distributed beans shouldn't call close on
their RPC counterparts. Patch is attached.
