distributed search improvement
------------------------------
Key: NUTCH-38
URL: http://issues.apache.org/jira/browse/NUTCH-38
Project: Nutch
Type: Improvement
Components: searcher, web gui
Reporter: Sami Siren
Assigned to: Sami Siren
Priority: Minor
Attachments: fault_tolerance.patch
Running nutch web application with separate search servers can be pain to
manage. Search servers go down, new segments are added, old ones removes and so
on, almost all of these actions require some work to be done also at web app
level (restart usually helps).
This simple enhancement tries to makes it just a little bit easier adding
following features:
-new segments can be added to searchservers without restarting the frontend.
-defective search servers are not queried until tey come back online
-watchdog keeps an eye for your searchservers and writes a simple log abt
statistics
