That's from my log. A preliminary investigation follows, with steps and
results pasted:
1. check the nutch-0.7.1 war file for the relevant class:
% jar tvf ./nutch-0.7.1.jar | grep Protocol
server: 2:14pm % jar tvf ./nutch-0.7.1.jar | grep Protocol.class
756 Tue Mar 07 13:17:04 PST 2006
org/apache/nutch/mapReduce/InterTrackerProtocol.class
491 Tue Mar 07 13:17:04 PST 2006
org/apache/nutch/mapReduce/JobSubmissionProtocol.class
324 Tue Mar 07 13:17:04 PST 2006
org/apache/nutch/mapReduce/MapOutputProtocol.class
409 Tue Mar 07 13:17:04 PST 2006
org/apache/nutch/mapReduce/TaskUmbilicalProtocol.class
517 Tue Mar 07 13:17:04 PST 2006 org/apache/nutch/protocol/Protocol.class
469 Tue Mar 07 13:17:04 PST 2006
org/apache/nutch/searcher/DistributedSearch$Protocol.class
So it indeed exists.
2. ... Perhaps, it wasn't found in the source tree...
find ./src/java -name 'Protocol.java' -print
server: 2:14pm % find ./src -name 'Protocol.java' -print [~/nutch-
0.7.1]
./src/java/org/apache/nutch/protocol/Protocol.java
Now I'm stumped... Help!
