inconsistency between configuration and source code

[Tianwei Sheng]

Hi,

When I tried to change the hbase table name into other names, from the
default "webpage" into "nutch_test_table" for example, I found there are
one inconsistency between configuration value and the code.

in the nutch-default, it has:
<property>
  <name>storage.schema</name>
  <value>webpage</value>
  <description>This value holds the schema name used for Nutch web db.
  Note that Nutch ignores the value in the gora mapping files, and uses
  this as the schema name.
  </description>
</property>

but in the code:
src/java/org/apache/nutch/storage/StorageUtils.java:
schema = conf.get("storage.schema.webpage", "webpage");

Whenever I changed the name in config, it always will use webpage as schema
and get the following warning:
"
store.HBaseStore - Keyclass and nameclass match but mismatching table names
 mappingfile schema is 'nutch_test_table' vs actual schema 'webpage' ,
assuming they are the same.
""

When I change the code into:
Index: src/java/org/apache/nutch/storage/StorageUtils.java

     String schema = null;
     if (WebPage.class.equals(persistentClass)) {
-      schema = conf.get("storage.schema.webpage", "webpage");
+      schema = conf.get("storage.schema", "webpage");
     } else if (Host.class.equals(persistentClass)) {
       schema = conf.get("storage.schema.host", "host");
     } else {


It works well.  I think we should change either  the code or default config
items. Not sure it's a known problem or it's just not recommended to use
other tables.
