[jira] [Created] (SOLR-3999) No serialVersionUID in SolrInputDocument and SolrInputField

yuanyun.cn created SOLR-3999:
--------------------------------

             Summary: No serialVersionUID in SolrInputDocument and SolrInputField
                 Key: SOLR-3999
                 URL: https://issues.apache.org/jira/browse/SOLR-3999
             Project: Solr
          Issue Type: Bug
          Components: search
    Affects Versions: 4.0, 3.6
            Reporter: yuanyun.cn
             Fix For: 4.1


In my solr server, one field is binarydoc which stores a SolrInputDocument; it contains some essential fields. - We do this to improve the transfer performance and some other desgin consideration, when copy the index of one document to another solr server, we only need copy the binarydoc field.

But when the client(3.6) and server(3.1) are not at same version, this would fail with error:
java.io.InvalidClassException: org.apache.solr.common.SolrInputDocument; local class incompatible: stream classdesc serialVersionUID = -933324331332362318, local class serialVersionUID = 7513968456965125205L4675759

The root cause if that SolrInputDocument doesn't provide a default serialVersionUID, and different version has different serialVersionUID.

When client is 4.0, server is 3.1, it report one more error:
java.io.InvalidClassException: org.apache.solr.common.SolrInputField; local class incompatible: stream classdesc serialVersionUID = -837387721983293523, local class serialVersionUID = 6061428683263691882
6061428683263691882

I temporarily fixed the error by adding serialVersionUID to client and server code with same value.

Please fix this :)
