Hi, I have configured HBase-0.20.0 with Hadoop-0.20.1 and HDFS. I have created one table named 'Employee'. some reason i restarted the Hbase then i executed "list" command to see available table in HBase but it didn't show me the previously created table "Employee". Then i checked with the command $HADOOP_HOME/bin/hadoop dfs -ls /hbase it show me the "Employee" table.
I have writen one java programme wich takes the table row name and displays the value column value. link for the java proframme http://old.nabble.com/file/p26192066/EmployeeImport.java EmployeeImport.java Facing Problem :- when i ran the above programme i got following exception table not found but table is available in HBase-HDFS. ********************************Exception*************************************** org.apache.hadoop.hbase.TableNotFoundException: EmployeeName at org.apache.hadoop.hbase.client.HConnectionManager$TableServers.locateRegionInMeta(HConnectionManager.java:632) at org.apache.hadoop.hbase.client.HConnectionManager$TableServers.locateRegion(HConnectionManager.java:586) at org.apache.hadoop.hbase.client.HConnectionManager$TableServers.locateRegion(HConnectionManager.java:549) at org.apache.hadoop.hbase.client.HTable.<init>(HTable.java:125) at org.apache.hadoop.hbase.client.HTable.<init>(HTable.java:103) at EmployeeImport$InnerMap.configure(EmployeeImport.java:62) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.apache.hadoop.util.ReflectionUtils.setJobConf(ReflectionUtils.java:88) at org.apache.hadoop.util.ReflectionUtils.setConf(ReflectionUtils.java:64) at org.apache.hadoop.util.ReflectionUtils.newInstance(ReflectionUtils.java:117) at org.apache.hadoop.mapred.MapRunner.configure(MapRunner.java:34) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.apache.hadoop.util.ReflectionUtils.setJobConf(ReflectionUtils.java:88) at org.apache.hadoop.util.ReflectionUtils.setConf(ReflectionUtils.java:64) at org.apache.hadoop.util.ReflectionUtils.newInstance(ReflectionUtils.java:117) at org.apache.hadoop.mapred.MapTask.runOldMapper(MapTask.java:354) at org.apache.hadoop.mapred.MapTask.run(MapTask.java:307) at org.apache.hadoop.mapred.LocalJobRunner$Job.run(LocalJobRunner.java:176) 09/11/04 12:41:40 INFO EmployeeImport: --------------------map called--------------------------- 09/11/04 12:41:40 WARN mapred.LocalJobRunner: job_local_0001 java.io.IOException: table is null at EmployeeImport$InnerMap.map(EmployeeImport.java:41) at EmployeeImport$InnerMap.map(EmployeeImport.java:33) at org.apache.hadoop.mapred.MapRunner.run(MapRunner.java:50) at org.apache.hadoop.mapred.MapTask.runOldMapper(MapTask.java:358) at org.apache.hadoop.mapred.MapTask.run(MapTask.java:307) at org.apache.hadoop.mapred.LocalJobRunner$Job.run(LocalJobRunner.java:176) 09/11/04 12:41:40 INFO mapred.JobClient: map 0% reduce 0% 09/11/04 12:41:40 INFO mapred.JobClient: Job complete: job_local_0001 09/11/04 12:41:40 INFO mapred.JobClient: Counters: 0 Exception in thread "main" java.io.IOException: Job failed! at org.apache.hadoop.mapred.JobClient.runJob(JobClient.java:1252) at EmployeeImport.run(EmployeeImport.java:103) at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:65) at EmployeeImport.main(EmployeeImport.java:118) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.apache.hadoop.util.RunJar.main(RunJar.java:156) -- View this message in context: http://old.nabble.com/Configured-HBase-with-HDFS-%3A--when-look-up-for-table-getting-org.apache.hadoop.hbase.TableNotFoundException-tp26192066p26192066.html Sent from the HBase User mailing list archive at Nabble.com.
