This is a nasty exception which kicked off my reducer task, which updates my MySQL table with the reducer output.
The reason behind this is unicode character.
MySQL table was created with non-unicode wester encoding. I’m trying to insert multi lingual unicode text. After changing the table collation (if needed field collation also) to utf8_bin, it worked fine.
alter table FeedEntryRecord convert to character set utf8 collate utf8_bin;
