Hi all -- we're currently on cdh3u3 (0.90.4 + patches). I have one table in our cluster which seems to functioning fine (gets/puts/scans are all working), but for which no regions are listed on the UI. The table/regions exist in .META. Other tables in the same cluster show their regions list fine. Seems like this might be a problem with .META. or ZK, but would appreciate any pointers.
1) hbase hbck reports 2 "multiply assigned to region servers" inconsistencies, but on a table different than the one I'm having problems with. 2) The hbase master log shows this fragment when navigating to table.jsp for the affected table: 2012-09-10 11:29:07,682 DEBUG org.apache.zookeeper.ClientCnxn: Reading reply sessionid:0x1370e3604c49580, packet:: clientPath:null serverPath:null finished:false header:: 10,4 replyHeader:: 10,167713215,-101 request:: '/hbase/table/sessions,F response:: 2012-09-10 11:29:07,682 DEBUG org.apache.hadoop.hbase.zookeeper.ZKUtil: hconnection-0x1370e3604c49580 Unable to get data of znode /hbase/table/sessions because node does not exist (not an error) 2012-09-10 11:29:07,682 DEBUG org.apache.hadoop.hbase.client.MetaScanner: Scanning .META. starting at row=sessions,,00000000000000 for max=2147483647 rows But since I see this "Unable to get data of znode" for all tables, my assumption is that it's a red herring. Any thoughts as how to debug further, or why only this table would not show a region list? Norbert
