I think what we have here is a basic Java error, nothing specific to
Solr. This jumps out at me:
Caused by: java.lang.NoSuchMethodException:
com.mytest.tokenizer.RelationChunkTokenizerFactory.<init>(java.util.Map)
at java.lang.Class.getConstructor0(Unknown Source)
at java.lang.Class.getConstructor(Unknown Source)

org.apache.solr.core.SolrResourceLoader.newInstance(SolrResourceLoader.java:552)

Java is trying to execute a method that doesn't exist. The
"getConstructor" pieces after the message suggest that perhaps it's a
constructor with a Map as an argument, but I'm not familiar enough with
this error to know whether it's trying to run a constructor that doesn't
exist, or whether it's trying to actually use a method called "init".
The constructor in TokenizerFactory is protected, and all of the
existing descendants that I looked at have a public constructor ... this
message would make sense in all of the following situations:
1) You didn't create a constructor for your object with a Map argument.
2) You made your constructor protected.
3) You made your constructor private.
Thanks,
