Metadata tries to write null values
-----------------------------------
Key: NUTCH-406
URL: http://issues.apache.org/jira/browse/NUTCH-406
Project: Nutch
Issue Type: Bug
Affects Versions: 0.9.0
Reporter: Doğacan Güney
During parsing, some urls (especially pdfs, it seems) may create <some_key,
null> pairs in ParseData's parseMeta.
When Metadata.write() tries to write such a pair, it causes an NPE.
Stack trace will be something like this:
at org.apache.hadoop.io.Text.encode(Text.java:373)
at org.apache.hadoop.io.Text.encode(Text.java:354)
at org.apache.hadoop.io.Text.writeString(Text.java:394)
at org.apache.nutch.metadata.Metadata.write(Metadata.java:214)
I can consistently reproduce this using the following url:
