This UUID is used to uniquely > identify a Drillbit and register Drillbit information in the RM StateBlobs. > Introduced a PersistentStore named ZookeeperTransactionalPersistenceStore > with Transactional capabilities using Zookeeper Transactional API’s. This is > used for updating RM State blobs as all the updates need to happen in > transactional manner. Added RMStateBlobs definition and support for serde to > Zookeeper. > Implementation for DistributedRM and its corresponding QueryRM apis and state > management. > Updated the state management of Query in Foreman so that same Foreman object > can be submitted multiple times. Also introduced concept of 2 maps keeping > track of waiting and running queries. These were done to support for async > admit protocol which will be needed with Distributed RM. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
