-----------------------
Resolution: Invalid
> SolrCloud 4.5 bulk add errors
> -----------------------------
>
> Key: SOLR-5331
> URL: https://issues.apache.org/jira/browse/SOLR-5331
> Project: Solr
> Issue Type: Bug
> Components: SolrCloud
> Affects Versions: 4.5
> Reporter: Chris
> 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.
