stack commented on HBASE-2036:
------------------------------
Tracking down why TestMergeTool is failing. Its a messy test particularly in
how it does its setup. Here is the failure mode:
{code}
Testcase: testMergeTool took 10.931 sec
Caused an ERROR
null
java.lang.NullPointerException

> Use Configuration instead of HBaseConfiguration

> Key: HBASE-2036
> URL: https://issues.apache.org/jira/browse/HBASE-2036
> Project: Hadoop HBase
> Issue Type: Improvement
> Reporter: Enis Soztutar

> HBaseConfiguration extends Configuration but does not add any functionality
> to it. The only function is hashCode() which really should be refactored into
> Hadoop Configuration.
> I think in all the places(especially in the client side) HBase methods and
> classes should accept Configuration rather than HBaseConfiguration. The
> creation of the configuration with the right files (hbase-site and
> hbase-default) should not be encapsulated in a private method, but in a
> public static one.
> The issues has arisen in our nutch+hbase patch for which we include both
> nutch configuration and hbase configurations. Moreover people may want to
> include separate project-specific configuration files to their configurations
> without the need to be dependent on the HBaseConfiguration.
