Hi, after upgrading from 0.20.3 to 0.20.4 a list of tables almost immediately becomes inconsistent - master.jsp shows no tables even after creating test table in hbase shell, tables which were available before start randomly appearing and disappearing, etc. Upgrading was done by stopping, upgrading code, and then starting (no dump/restore was done). I didn't investigate yet, just checking if somebody had the same problem or if I did upgrade right (I had exactly the same issue in the past when trying to apply HBASE-2174 manually).
Environment: Small tables, <100k rows Amazon EC2, "c1.xlarge" instance type with Ubuntu 9.10 and EBS root, HBase installed manually 1 master (namenode + jobtracker + master), 3 slaves (tasktracker + datanode + regionserver + zookeeper) Hadoop 0.20.1+169.68~1.karmic-cdh2 from Cloudera distribution Flaky DNS issue present, happens about once per day even with dnsmasq installed (heartbeat every 1s, dnsmasq forwards requests once per minute), DDNS set for internal hostnames. This is a testing cluster, nothing important on it. Cheers, -- Viktors
