>             Project: HBase
>          Issue Type: Bug
>          Components: documentation
>    Affects Versions: 1.0.0

> I'm trying to build and run the example java code I found in the HBase Documentation, and I'm running into several issues.
> 1. I don't have the code/library used in the following import:
> import static com.example.hbase.Constants.*;
> I don't believe it is included in any of the HBase libraries or documentation.
> 2. All of the methods in createOrOverwrite() that use table.getName() should instead be using table.getTableName()
> 3. The interface org.apache.hadoop.hbase.client.Admin is abstract, and can't be instantiated with a Configuration. Constructing an org.apache.hadoop.hbase.client.HBaseAdmin would allow the code to compile, but that constructor is deprecated.
> 4. I have no references to the field "TABLE_NAME" or "CF_DEFAULT". I'm assuming they are Strings in com.example.hbase.Constants. Perhaps those variables should simply be copied into the the Example?
