-------------------------------
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.
