Hi, Included Content.java. Will retry with latest trunk shortly.
Content.java:137-149
137 protected final void writeCompressed(DataOutput out) throws
IOException {
138 out.writeByte(VERSION);
139
140 Text.writeString(out, url); // write url
141 Text.writeString(out, base); // write base
142
143 out.writeInt(content.length); // write content
144 out.write(content);
145
146 Text.writeString(out, contentType); // write contentType
147
148 metadata.write(out); // write metadata
149 }
I also noticed in the output.collect call in Fetcher.java a new
FetcherOutput is created with the third argument (ParseImpl) as null
even though the Content argument is not null (it is the contents of the
page that is redirected to).
Cheers,
Carl.
