Prior to this commit, SuggestComponent used a HashMap as part of the
response it built on the server side. This class is serialized/
deserialized differently depending on the SolrJ ResponseParser used:
a LinkedHashMap when javabin was used, and a SimpleOrderedMap when XML
was used. This discrepancy led to ClassCastException's in downstream
SolrJ code.
This commit fixes the issue by changing SuggestComponent to avoid these
types that are serialized differently. "suggest" response sections now
deserialize as a NamedList in SolrJ, and the SuggesterResponse POJO has
been updated accordingly.
* When the schema defines _root_, and you want to do atomic/partial updates...
** _root_ needn't be stored or have docValues any more
** _nest_path_ field isn't needed for this any more
** Simplified internal logic
* Allow (and recommend, eventually insist) that the _root_ field be passed for atomic/partial updates to child docs.
** In the absence of _root_, assume the _route_ param is equivalent to ameliorate back-compat scope. This is a temporary hack; remove in SOLR-15064.
** One of the two is required; you'll get an exception if the assumption is false. THIS IS A BACK-COMPAT CHANGE
* Ensure that the update log contains the _root_ field if it's defined in the schema; in some cases it wasn't. It's important for robustness of atomic/partial updates to child docs. Caveat: the buffer replay scenario is not tested with child docs.
* Limited the cases when a realtime searcher is re-opened. It was being applied to any update that included child docs but now only some narrow subset: only for atomic/partial updates, and when the update log contains an in-place update for the same nest because it's complicated to resolve those log entries.
* Internal improvements to RealTimeGetComponent to aid clarity & robustness & probably performance...
** Use SolrDocumentFetcher.solrDoc(docID, ReturnFields) instead of more manual loading. Will do more with this in another PR.
** Clarify when only root doc IDs are expected.
** Use Resolution enum more, add PARTIAL, remove DOC_WITH_CHILDREN; enhance docs.
** When have ReturnFields, a Set of "onlyTheseFields" becomes redundant. Add a child doc resolution via a transformer when needed.
** Clarified where copy-field targets are removed
* NestPathField should default to single valued, instead of inheriting the schema default, which for ancient schemas was multi-valued.
* AddUpdateCommand.getLuceneDocument(s) methods are very internal; made package visible and refactored a bit for clarity
* DocumentBuilder: when in-place update, skip id and _root_ here, thus also simplifying further logic
* NestedShardedAtomicUpdateTest no longer extends AbstractFullDistribZkTestBase because it wasn't really leveraging the "control client" checking, and it added too much complexity to debug failures.
SOLR-13027 Use TestInjection so that we always have a Tragic Event
When we encounter a tragic error in the index writer, we can trigger a
leader election instead of queing up a delete and re-add of the node in
question. This should result in a more graceful transition, and the
previous leader will eventually be put into recovery by a new leader.
closes#2120
* Remove distrib=false from /terms handler so that terms are returned from across all shards instead of a single local shard.
* cleanup shards parameter handling in TermsComponent. This is handled in HttpShardHandler
* Remove redundant tests for shard whitelist
* remove redundant terms params from ScoreNodeStream
When set to true, Solr will overwrite an existing configset in ZooKeeper in an UPLOAD.
A new cleanup parameter can also be passed to let Solr know what to do with the files that existed in the old configset, but no longer exist in the new configset (remove or keep)
