------------------------------------------
Summary: Repl Scale Test : Running long running load
(incr/bootstrap) causing OOM error
Key: HIVE-20329
URL: https://issues.apache.org/jira/browse/HIVE-20329
Project: Hive
Issue Type: Task
Components: repl
Affects Versions: 3.1.0, 4.0.0
Reporter: mahesh kumar behera
Assignee: mahesh kumar behera
Fix For: 4.0.0, 3.2.0
Add tags in jobconf for distcp related jobs started by replication. This will
allow hive to kill these jobs in case beacon retries, or hs2 dies and beacon
issues a kill command.
* one of the tags should definitely be the query_id that starts the job : With
this flow beacon before retrying the bootstrap load, will issue a kill command
to hs2 with the query id of the previous issued command. hs2 will then kill an
running jobs on yarn tagged with the Query_id.
* To get around the additional failure point as mentioned above. The jobs can
be tagged with an additional unique tag_id provided by Beacon in the WITH
clause in repl load command to be used to tag distcp jobs ). Enhance the kill
api to take the tag as input and kill jobs associated with that tag. Problem
here is how do we validate the association of the tag with a hive query id to
make sure this api is not used to kill jobs run by other components, however we
can provide this capability to only admins and should be ok in that case.
