NullPointerException in
piggybank.evaluation.util.apachelogparser.SearchTermExtractor
-------------------------------------------------------------------------------------
Key: PIG-2110
URL: https://issues.apache.org/jira/browse/PIG-2110
Project: Pig
Issue Type: Bug
Affects Versions: 0.8.0
Reporter: Michael Brauwerman
When processing a large log file, I get an exception in SearchTermExtractor.exec
I don't have a specific log line with a repro yet, but I assume the error
occurs when the input URL is null, or maybe just has no query string:
I think a fix would be to be add a guard after creating queryString:
String queryString = urlObject.getQuery();
if (queryString == null) { return null; }
Stack Trace:
