Which hbase release are you using ? Can you check master log to see if there is some clue w.r.t. LoadTest ?
Using "hbase zkcli", you can inspect the znode status. Below is a sample: [zk: cn011.x.com:2181,cn013.x.com:2181,cn012.x.com:2181(CONNECTED) 2] ls /hbase-unsecure/table [hbase:meta, hbase:namespace, IntegrationTestBigLinkedList, datatsv, usertable, hbase:backup, TestTable, t2] [zk: cn011.x.com:2181,cn013.x.com:2181,cn012.x.com:2181(CONNECTED) 3] ls /hbase-unsecure/table/2 Node does not exist: /hbase-unsecure/table/2 [zk: cn011.x.com:2181,cn013.x.com:2181,cn012.x.com:2181(CONNECTED) 4] ls /hbase-unsecure/table/t2 [] [zk: cn011.x.com:2181,cn013.x.com:2181,cn012.x.com:2181(CONNECTED) 5] get /hbase-unsecure/table/t2 �master:16000K��W�,�PBUF cZxid = 0x1000a7f01 ctime = Mon Mar 27 16:50:52 UTC 2017 mZxid = 0x1000a7f17 mtime = Mon Mar 27 16:50:52 UTC 2017 pZxid = 0x1000a7f01 cversion = 0 dataVersion = 2 On Tue, Apr 25, 2017 at 4:09 PM, jeff saremi <[email protected]> wrote: > BTW on the page > http://localhost:16010/master-status#userTables > there is no sign of the supposedly existing table either > > ________________________________ > From: jeff saremi <[email protected]> > Sent: Tuesday, April 25, 2017 4:05:56 PM > To: [email protected] > Subject: Baffling situation with tableExists and createTable > > I have a super simple piece of code which tries to create a test table if > it does not exist > > calling admin.tableExists(TableName.valueOf(table)) returns false causing > the control to be passed to the line that creates it > admin.createTable(tableDescriptor). > Then i get an exception that the table exists! > > Exception in thread "main" org.apache.hadoop.hbase.TableExistsException: > LoadTest > > > String table = config.tableName; > ... > Connection conn = ConnectionFactory.createConnection(hbaseconf); > Admin admin = conn.getAdmin(); > if(!admin.tableExists(TableName.valueOf(table))) { > Log.info("table " + table + " does not exist.
