Jesse Yates created HBASE-6495:
----------------------------------
Summary: HBaseAdmin shouldn't expect HConnection to be an
HConnectionImplementation
Key: HBASE-6495
URL: https://issues.apache.org/jira/browse/HBASE-6495
Project: HBase
Issue Type: Bug
Affects Versions: 0.96.0, 0.94.1
Reporter: Jesse Yates
Fix For: 0.96.0, 0.94.1
Currently, the HBaseAdmin has a constructor that takes an HConnection, but then
immediately casts it to an HConnectionManager.HConnectionImplementation:
{code}
public HBaseAdmin(HConnection connection)
throws MasterNotRunningException, ZooKeeperConnectionException {
this.conf = connection.getConfiguration();
// We want the real class, without showing it our public interface,
// hence the cast.
this.connection = (HConnectionManager.HConnectionImplementation)connection;
{code}
However, this breaks the explicit contract in the javadocs and makes it
basically impossible to mock out the hbaseadmin.
We need to either make the hbaseadmin use a basic HConnection and optimize for
cases where its smarter or bring up the couple of methods in
HConnectionManager.HConnectionImplementation to the HConnection interface.
