It shows up in different jobs and we can reprocess the same data with no problems. Our theory is that HBase may be migrating a region to a different server while the scanner is reading it. Perhaps there is some setting we can enable to prevent this? Here's the stack trace we get: http://pastebin.com/Wh3ZBC0J Any insight is appreciated, let me know if you would like me to gather any other log data. Thanks, Jim --001a11c1317cef2daf04f971d30a--
