--------------------------------
Summary: Consider concurrency situations for TimelineWriter
Key: YARN-3650
URL: https://issues.apache.org/jira/browse/YARN-3650
Project: Hadoop YARN
Issue Type: Sub-task
Reporter: Vrushali C
[~jrottinghuis] brought up an interesting point in YARN-3411. Filing jira to
track to discuss and handle the following:
For TimelineWriter and its implementations, is there an expectation set around
concurrency? Is any synchronization expected / needed to ensure visibility when
calls happen from different threads?
How about entities, are they expected to be immutable once passed to the write
method?
Similarly for the constructor, we're assuming that the configuration object
will not be modified while we're constructing a TimelineWriter?
