Apache Spark reassigned SPARK-6716:
-----------------------------------
Assignee: Apache Spark (was: Josh Rosen)
> Change SparkContext.DRIVER_IDENTIFIER from '<driver>' to 'driver'
> -----------------------------------------------------------------
>
> Key: SPARK-6716
> URL: https://issues.apache.org/jira/browse/SPARK-6716
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Reporter: Josh Rosen
> Assignee: Apache Spark
>
> Currently, the driver's executorId is set to {{<driver>}}. This choice of ID
> was present in older Spark versions, but it has started to cause problems now
> that executorIds are used in more contexts, such as Ganglia metric names or
> driver thread-dump links the web UI. The angle brackets must be escaped when
> embedding this ID in XML or as part of URLs and this has led to multiple
> problems:
> - https://issues.apache.org/jira/browse/SPARK-6484
> - https://issues.apache.org/jira/browse/SPARK-4313
> The simplest solution seems to be to change this id to something that does
> not contain any special characters, such as {{driver}}.
> I'm not sure whether we can perform this change in a patch release, since
> this ID may be considered a stable API by metrics users, but it's probably
> okay to do this in a major release as long as we document it in the release
> notes.
