Subject Configured HBase with HDFS :- when look up for table getting org.apache.hadoop.hbase.TableNotFoundException
Date Wed, 04 Nov 2009 07:31:47 GMT

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.
