It looks like the "HRegionInfo was null or empty in .META." bug has reappeared in RC1. We're trying to do a large load -- 100GB on 19 nodes. Our boxes are 8 core, 8 GB RAM, and we've tuned the GC and kernel with every suggestion I found in the wiki and mailing list.
I've included every log I can think of : https://www.yousendit.com/download/Y1RyTmZVdVU1bml4dnc9PQ "org.apache.hadoop.hbase.client.RetriesExhaustedException: Trying to contact region server Some server for region , row 'E3652782193BC8D66A0BA1629D0FAAAB', but failed after 11 attempts.
