             Summary: CLONE - SolrCloud 4.5 bulk add errors
                 Key: SOLR-5402
                 URL: https://issues.apache.org/jira/browse/SOLR-5402
             Project: Solr
          Issue Type: Bug
          Components: SolrCloud
    Affects Versions: 4.5
            Reporter: Sai Gadde
             Fix For: 4.5.1


Since Solr 4.5 bulk adding documents via SolrJ (at least) is causing errors.

// build array list of SolrInputDocuments

server.add(docs);

I've tried with CUSS (which swallows exceptions as expected) however they are shown in the logs on server, and with CloudSolrServer which is returning the errors as well as seeing them in the server logs.

I've tried downgrading my SolrJ to 4.4, still errors so looks like a regression in the server code. Reverting to Solr 4.4 on server and I don't get errors (however run into deadlock issues).

I raised this issue in IRC - NOT the mailing list, and elyorag suggested opening a ticket, and to mention this has now been discussed in IRC.

The exceptions would indicate I'm attempting to do multiple operations in a single request which is malformed. I am not, I am only attempting to add documents.
