Description

I think we should put these configurations in the HConstants class to avoid the trouble of modifying a lot of places when we modify them later.

public static final String MASTER_KRB_PRINCIPAL = "hbase.master.kerberos.principal";
public static final String MASTER_KRB_KEYTAB_FILE = "hbase.master.keytab.file";
public static final String REGIONSERVER_KRB_PRINCIPAL = "hbase.regionserver.kerberos.principal";
public static final String REGIONSERVER_KRB_KEYTAB_FILE = "hbase.regionserver.keytab.file";
