Subject [jira] [Commented] (SOLR-3950) Attempting postings="BloomFilter" results in UnsupportedOperationException
Date Tue, 16 Oct 2012 13:49:04 GMT

    [ https://issues.apache.org/jira/browse/SOLR-3950?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13476999#comment-13476999
] 

Shawn Heisey commented on SOLR-3950:
------------------------------------

bq. However your code has instantiated a BloomFilterPostingsFormat without passing a choice
of delegate - presumably using the zero-arg constructor. 

In this case, "my" code is Solr, source code unmodified.  From my schema.xml:

{code}
<fieldType name="bloomLong" class="solr.TrieLongField" precisionStep="0" omitNorms="true"
positionIncrementGap="0" postingsFormat="BloomFilter"/>
<fieldType name="bloomLowercase" class="solr.TextField" sortMissingLast="true" positionIncrementGap="0"
omitNorms="true" postingsFormat="BloomFilter">
.
. <snip>
.
</fieldType
{code}

If there is some schema config that will tell Solr to do the right thing, please let me know.

> I used 'ant generate-maven-artifacts' to create the lucene-codecs jar, and copied it
into my sharedLib directory.  When I subsequently tried postings="BloomFilter" I got a the
following exception in the log:

> SEVERE: java.lang.UnsupportedOperationException: Error - org.apache.lucene.codecs.bloom.BloomFilteringPostingsFormat
has been constructed without a choice of PostingsFormat
