> Key: DRILL-7191
> URL: https://issues.apache.org/jira/browse/DRILL-7191
> Project: Apache Drill
> Issue Type: Sub-task
> Components: Server, Query Planning & Optimization
> Affects Versions: 1.17.0
> Reporter: Hanumath Rao Maduri
> Assignee: Sorabh Hamirwasia
> Priority: Major
> Fix For: 1.17.0
>
>
> Changes to support storing UUID for each Drillbit Service Instance locally to
> be used by planner and execution layer. 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.
