Does anybody have any thoughts on this? It seems similar to the NUTCH-1016 bug
that was fixed in version 1.4.
Some more bits of information: the indexer job rarely fails (only 1 of the last
99 segments) but the cleaning job fails every time now. Once again, this is
Nutch 1.12 and Solr 5.4.1. I recently upgraded to hadoop 2.7.4 and Java 1.8
from Hadoop 2.7.2 and java 1.7. Could this be some kind of mismatch of versions?

Subject: invalid utf8 chars when indexing or cleaning
Lately, I have seen many tasks and jobs fail in Solr when doing nutch index and
nutch clean.
Messages during indexing look like this.

Can anyone suggest a way to fix this? I am using nutch 1.12 and Solr 5.4.1. I
recently upgraded to hadoop 2.7.4 and Java 1.8. I don't remember noticing this
happening with Hadoop 2.7.2 and java 1.7. It happens very often now.
