   Hi @lewismc. Thank you for your review.
   
   Sorry for my late reply.
   I have tried the new stores of Gora 0.7, results are below.
   
   | DataStore | Result | Description |
   |-----------|---------|-------------|
   | JCache     | NG         |  Preparing patch for Gora |
   | Infinispan  | NG        | Under investigation. Error occurred in client |
   | CouchDB  | NG         | Problem with update the document. Is MapReduce 
unsupported?※ |
   | DynamoDB | NG       | Conflicting with AWS client library. Is MapReduce 
unsupported?※ |
   
   ※There is no MapReduce integration test in the repository of Gora 0.7.
   
   JCacheStore works by rebuild classes of storage and applying patch to Gora 
to disable CacheEntryListener,
   Others are under investigation.
   
   By the way, with HBaseStore at this PR code base, It worked.
   InfinispanStore is investigating, but it takes much time. May I assume that 
CouchDB and DynamoDB are out of the scope Nutch 2.4?
