Method Details

isDistributedCollectionAPI

public boolean isDistributedCollectionAPI()

Description copied from interface: CollectionCommandContext

When this method returns true, Overseer specific actions do not make sense and commands should not be doing them.

Specified by:

isDistributedCollectionAPI in interface CollectionCommandContext

newShardHandler

public ShardHandler newShardHandler()

Specified by:

newShardHandler in interface CollectionCommandContext

getSolrCloudManager

public org.apache.solr.client.solrj.cloud.SolrCloudManager getSolrCloudManager()

Specified by:

getSolrCloudManager in interface CollectionCommandContext

getCoreContainer

public CoreContainer getCoreContainer()

Specified by:

getCoreContainer in interface CollectionCommandContext

getZkStateReader

public org.apache.solr.common.cloud.ZkStateReader getZkStateReader()

Specified by:

getZkStateReader in interface CollectionCommandContext

getDistributedClusterStateUpdater

public DistributedClusterStateUpdater getDistributedClusterStateUpdater()

Specified by:

getDistributedClusterStateUpdater in interface CollectionCommandContext

offerStateUpdate

public void offerStateUpdate(byte[] data)
                      throws org.apache.zookeeper.KeeperException,
InterruptedException

Description copied from interface: CollectionCommandContext

This method enables the commands to enqueue to the overseer cluster state update. This should only be used when the cluster state update is running in the Overseer (and will throw an exception if called when Collection API is distributed given that distributed Collection API implies distributed Cluster State Update)

Specified by:

offerStateUpdate in interface CollectionCommandContext

Throws:

org.apache.zookeeper.KeeperException

InterruptedException

offerStateUpdate

public void offerStateUpdate(org.apache.solr.common.MapWriter mw)
                      throws org.apache.zookeeper.KeeperException,
InterruptedException

Specified by:

offerStateUpdate in interface CollectionCommandContext

Throws:

org.apache.zookeeper.KeeperException

InterruptedException

getCloseableToLatchOn

public org.apache.solr.common.SolrCloseable getCloseableToLatchOn()

Specified by:

getCloseableToLatchOn in interface CollectionCommandContext

getExecutorService

public ExecutorService getExecutorService()

Specified by:

getExecutorService in interface CollectionCommandContext

getOverseerId

public String getOverseerId()

Specified by:

getOverseerId in interface CollectionCommandContext

getOverseerStats

public Stats getOverseerStats()

Description copied from interface: CollectionCommandContext

Command delegating to Overseer to retrieve cluster state update stats from a Collection API call. This does not make sense when cluster state updates are distributed given Overseer does not see them and can't collect stats.

Specified by:

getOverseerStats in interface CollectionCommandContext

submitIntraProcessMessage

public void submitIntraProcessMessage(Overseer.Message message)

Description copied from interface: CollectionCommandContext

Method used by Per Replica States implementation to force the cluster state updater to immediately reload a collection from Zookeeper. This method is not used when cluster state updates are distributed.

Specified by:

submitIntraProcessMessage in interface CollectionCommandContext
