[jira] [Commented] (SOLR-5970) Create collection API always has status 0

["Gregory Chanan (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SOLR-5970?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14000606#comment-14000606 ] 

Gregory Chanan commented on SOLR-5970:
--------------------------------------

I looked into this a bit.  It looks like the collection creation always returns status 0, and returns the failures of the individual shards in the "failure" field of the response and successes in "success."  That's interesting information, although I'm not sure it's that more useful for the end-user than just throwing an exception listing all the failures or just the first failure.

This also appears to be an issue with the other OverseerCollectionProcessor, although I'm not sure if there is any case where an individual operation is not successful, but we'd want to not throw an exception.  Anyone have an opinion?  [~markmiller]?

> The responses below are from a successful create collection API (https://cwiki.apache.org/confluence/display/solr/Collections+API#CollectionsAPI-CreateormodifyanAliasforaCollection) call and an unsuccessful create collection API call. It seems the 'status' is always 0.
> Success:
> {u'responseHeader': {u'status': 0, u'QTime': 4421}, u'success': {u'': {u'core': u'test1_shard1_replica1', u'responseHeader': {u'status': 0, u'QTime': 3449}}}}
> Failure:
> {u'failure': 
>   {u'': u"org.apache.solr.client.solrj.impl.HttpSolrServer$RemoteSolrException:Error CREATEing SolrCore 'test43_shard1_replica1': Unable to create core: test43_shard1_replica1 Caused by: Could not find configName for collection test43 found:[test1]"},
>  u'responseHeader': {u'status': 0, u'QTime': 17149}
> }
> It seems like the status should be 400 or something similar for an unsuccessful attempt?
