Sorabh Hamirwasia updated DRILL-7191:
-------------------------------------
Description:
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.
was:
Selection of the queue based on the acl/tags
Non-leader queue configurations
All required blobs for the queues in Zookeeper.
Concept of waiting queues and running queues on Foreman
Handling state transition of queryRM
