> Validate cache QueryEntities in discovery thread
> ------------------------------------------------
>
> Key: IGNITE-5380
> URL: https://issues.apache.org/jira/browse/IGNITE-5380
> Project: Ignite
> Issue Type: Task
> Components: cache, sql
> Reporter: Vladimir Ozerov
> Assignee: Alexander Paschenko
> Fix For: 2.1
>
>
> Consider the following case:
> 1) Execute SQL: TABLE Person ...}}
> 2) Then again: TABLE Person ...}}
> Second call will lead to exception in exchange thread and will hang the whole
> cluster.
> We need to add validation of {{CacheConfiguration.queryEntities}} wrt to
> other caches. This check should be performed in discovery thread. Note that
> we cannot rely on {{GridQueryProcessor}} or {{IgniteH2Indexing}} state, as
> some cache start requests may already be enqueued to exchange worker.
> Instead, we should perform cross-cache validation base only on two things:
> 1) {{DynamicCacheDescriptor.cacheCfg}}
> 2) {{DynamicCacheDescriptor.schema}}
> That is, we should resolve cache schema name from configuration, tables and
> indexes from schema, and then cross-validate them with other caches.
