Hi there, I've been trying to create HBase table by java code. Using HBase shell, I can see the table was created after running following codes, but there's exception raised. I don't know why it raised such exception in HBase0.20.2; these code run well in HBase0.20.0.
There are 3 region servers in my cluster; I can see these status correctly in http://ooxx:60010/master.jsp. (hadoop dfs running well too),(3 ZooKeeper quorum resides in the region server machine) By the wat, any steps that I can confirm my HBase is running well without any problems? Thanks public static void CreatHBaseTable(String TableName,String ColumnFamily){ HBaseAdmin hbaseAdmin; try { hbaseAdmin = new HBaseAdmin(config); HColumnDescriptor column = new HColumnDescriptor(ColumnFamily); //table descriptor HTableDescriptor table = new HTableDescriptor(TableName); //add column into table table.addFamily(column); hbaseAdmin.createTable(table); } catch (MasterNotRunningException e1) { // TODO Auto-generated catch block e1.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } System.out.println("create "+TableName +" ok"); } 09/12/08 16:09:49 INFO zookeeper.ClientCnxn: Server connection successful Exception in thread "main" java.lang.reflect.UndeclaredThrowableException at $Proxy1.getRegionInfo(Unknown Source) at org.apache.hadoop.hbase.client.HConnectionManager$TableServers.locateRootRegion(HConnectionManager.java:874) at org.apache.hadoop.hbase.client.HConnectionManager$TableServers.locateRegion(HConnectionManager.java:515) at org.apache.hadoop.hbase.client.HConnectionManager$TableServers.locateRegion(HConnectionManager.java:491) at org.apache.hadoop.hbase.client.HConnectionManager$TableServers.locateRegionInMeta(HConnectionManager.java:565) at org.apache.hadoop.hbase.client.HConnectionManager$TableServers.locateRegion(HConnectionManager.java:524) at org.apache.hadoop.hbase.client.HConnectionManager$TableServers.locateRegion(HConnectionManager.java:491) at org.apache.hadoop.hbase.client.HConnectionManager$TableServers.locateRegionInMeta(HConnectionManager.java:565) at org.apache.hadoop.hbase.client.HConnectionManager$TableServers.locateRegion(HConnectionManager.java:528) at org.apache.hadoop.hbase.client.HConnectionManager$TableServers.locateRegion(HConnectionManager.java:491) at org.apache.hadoop.hbase.client.HBaseAdmin.createTable(HBaseAdmin.java:169) at ClientMain.CreatHBaseTable(ClientMain.java:797) at ClientMain.main(ClientMain.java:65) Caused by: org.apache.hadoop.ipc.RemoteException: java.io.IOException: java.lang.NullPointerException at java.lang.Class.searchMethods(Class.java:2646) at java.lang.Class.getMethod0(Class.java:2670) at java.lang.Class.getMethod(Class.java:1603) at org.apache.hadoop.hbase.ipc.HBaseRPC$Server.call(HBaseRPC.java:643) at org.apache.hadoop.hbase.ipc.HBaseServer$Handler.run(HBaseServer.java:915) at org.apache.hadoop.hbase.ipc.HBaseClient.call(HBaseClient.java:723) at org.apache.hadoop.hbase.ipc.HBaseRPC$Invoker.invoke(HBaseRPC.java:328) ... 13 more --------------------------------------------------------------------------- TSMC PROPERTY This email communication (and any attachments) is proprietary information for the sole use of its intended recipient.
