Eric Wohlstadter updated TEZ-3991: ---------------------------------- Attachment: TEZ-3991.2.patch > Unmanaged tez sessions > ---------------------- > > Key: TEZ-3991 > URL: https://issues.apache.org/jira/browse/TEZ-3991 > Project: Apache Tez > Issue Type: New Feature > Affects Versions: 0.10.0 > Reporter: Prasanth Jayachandran > Assignee: Eric Wohlstadter > Priority: Major > Labels: Kubernetes > Attachments: TEZ-3991.1.patch, TEZ-3991.2.patch > > > Provide an option for launching tez AM in unmanaged mode. In unmanaged mode, > tez AMs can register itself with Zookeeper which clients (like HiveServer2) > can discover via zk registry client. > HiveServer2 currently manages the lifecycle of tez AMs. The unmanaged mode > will let AM come up on their own (can be via simple java launcher) and be > discoverable for others. > Example use case for this is, HiveServer2 can discover already running AMs > and can attach to it for DAG submission and detach when done executing > queries. AMs can similarly discover LLAP daemons via task scheduler plugin > for submitting tasks. > A mode to cut off interactions with RM will also useful since for LLAP no > on-demand containers are required. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
