             Summary: Solr in cloud mode silently fails uploading a big LTR model
                 Key: SOLR-11049
                 URL: https://issues.apache.org/jira/browse/SOLR-11049
             Project: Solr
          Issue Type: Bug
      Security Level: Public (Default Security Level. Issues are Public)
         Environment: tested with Solr 6.6 an integrated zookeeper
            Reporter: Stefan Langenmaier


Hi,

I'm using Solr in cloud mode, I have a MultipleAdditiveTreesModel with about 3MB in size. When I upload the model with

{noformat}
curl -v -XPUT 'http://localhost:8983/solr/tmdb/schema/model-store' --data-binary @/big-tree.model -H 'Content-type:application/json'
{noformat}


I get the following response

{code:html}
{
  "responseHeader":{
    "status":0,
    "QTime":24318}
}
{code}

This looks kind of slow but without an error. When I check the config the model is not visible and when I try to run a query that uses the model I get the following error

{code:html}
"error":{
    "metadata":[
      "error-class","org.apache.solr.common.SolrException",
      "root-error-class","org.apache.solr.common.SolrException"],
    "msg":"cannot find model bigTreeModel",
    "code":400}
{code}

When I upload the model to solr where I increased the zookeeper znode size limit with

{noformat}
-Djute.maxbuffer=0x1ffffff
{noformat}

the same model upload succeeds much faster

{code:html}
{
  "responseHeader":{
    "status":0,
    "QTime":689}
}
{code}

The model is visible in the configuration and queries that use it run without error.
