Dale Jin updated PIG-2110:
--------------------------
Attachment: SearchTermExtractor.diff
> 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
> Attachments: SearchTermExtractor.diff
>
> Original Estimate: 24h
> Remaining Estimate: 24h
>
> 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:
> <code>
> Caused by: java.io.IOException: Caught exception processing input row
> at
