Hello,
I get the following exception originating at line no 6 of the code snippet

Error occurs at line 6. of the code below.
1. HBaseConfiguration conf = new HBaseConfiguration();
2. conf.set(HConstants.REGION_SERVER_CLASS, TransactionalRegionInterface.class
.getName());
3. conf.set(HConstants.REGION_SERVER_IMPL, TransactionalRegionServer.class
.getName());
4. HTableDescriptor desc = new HTableDescriptor("testTable");
5. desc.addFamily(new HColumnDescriptor("testFamily"));
6. HBaseAdmin admin = new HBaseAdmin(conf);
7. admin.createTable(desc);
--------------------------------------------------------
Can I simply use src/contrib/transactional packages during compilation of my
application code ?
What other steps are required to use the transactional package ?
Iam using HBase-0.20.1 over hadoop-0.20.1
Thanks,
Naresh.
