i have a minhash logic that uses guava 18.0 method that is not in guava
14.0.1. This minhash logic is a separate maven project. I'm including it in
my project via maven.the code is being used as a search component on the
set of results. The logic goes through the search results and deletes
duplicates. here is the solrconfig.xml
<requestHandler name="/select" class="solr.SearchHandler" default="true"
>
<arr name="last-components">
<str>tvComponent</str>
<str>terms</str>
<str>minHashDedup</str>
</arr>
</requestHandler>
<searchComponent name="minHashDedup" class="com.xyz.DedupSearchHits"><str
name="MAX_COMPARISONS">5</str>
DedupSearchHits class is the one implementing the minhash (hence using
guava 18). I start solr via the solr.in.sh script. The error I am getting
is:
Caused by: java.lang.NoSuchMethodError:
com.google.common.hash.HashFunction.hashUnencodedChars(Ljava/lang/CharSequence;)Lcom/google/common/hash/HashCode;

What is the best design to solve this problem?I understand the point of
modularity but how can i include logic into solr that does result
processing without loading that jar into solr?
thank you
