> Consider concurrency situations for TimelineWriter
> --------------------------------------------------
>
> Key: YARN-3650
> URL: https://issues.apache.org/jira/browse/YARN-3650
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: timelineserver
> Reporter: Vrushali C
> Labels: YARN-5355
>
> [~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?
