use of org.elasticsearch.indices.breaker.HierarchyCircuitBreakerService in project crate by crate.

the class IndexShardTestCase method newShard.

/**
 * creates a new initializing shard.
 * @param routing                       shard routing to use
 * @param shardPath                     path to use for shard data
 * @param indexMetadata                 indexMetadata for the shard, including any mapping
 * @param storeProvider                 an optional custom store provider to use. If null a default file based store will be created
 * @param globalCheckpointSyncer        callback for syncing global checkpoints
 * @param indexEventListener            index event listener
 * @param listeners                     an optional set of listeners to add to the shard
