Is "UniqueKey" in schema and "pk" attribute for DataimportHandler entities still optional in solr 1.4?

[Alexandr Savochkin <al...@gmail.com>]

I allways build solr index from scratch, so I don't have neither "pk"
attribute in "entity" tag (dataconfig.xml file) nor "UniqueKey" in index
schema. When I updated solr from 1.3 to 1.4 I got the following exception
during solr initialization:

Is "UniqueKey" in schema still optional in solr 1.4? Is "pk" attribute in
still optional in solr 1.4 DataImportHandler entities?  As I can see in
org.apache.solr.handler.dataimport.DataImporter class source exception
allways occure when UniqueKey not specified for index schema.

It is (suppose to be) optional.  Some functionality requires is 
(QueryElevationComponent) but DataImportHandler is not (suppose to be) one 
of them.
