Nathan Gass created NUTCH-1490:
----------------------------------
Summary: Data Truncation exceptions when using mysql
Key: NUTCH-1490
URL: https://issues.apache.org/jira/browse/NUTCH-1490
Project: Nutch
Issue Type: Bug
Affects Versions: 2.1
Reporter: Nathan Gass
Nutch does not ensure the set (or implicit) maximal length for the following
columns:
title
urls (id, baseUrl, reprUrl,
typ (contentType)
inlinks
outlinks
Trying to store too much data in one of this columns results in an exception
similar to this (copied from GORA-24, I will be able to add an newer stack
trace later today):
java.io.IOException: java.sql.BatchUpdateException: Data truncation: Data too
long for column 'inlinks' at row 1

I'll add my current fixes in later comments.
