--------------------------------------

Sorry, [~hyukjin.kwon], I didn't realize that the Spark docs were built as part of the software.

> The [latest Spark documentation on the REST API|http://spark.apache.org/docs/latest/monitoring.html#rest-api] includes the following introductory paragraph:
> {quote}In the API, an application is referenced by its application ID, {{[app-id]}}. When running on YARN, each application may have multiple attempts, but there are attempt IDs only for applications in cluster mode, not applications in client mode. Applications in YARN cluster mode can be identified by their {{[attempt-id]}}. In the API listed below, when running in YARN cluster mode, {{[app-id]}} will actually be {{[base-app-id]/[attempt-id]}}, where {{[base-app-id]}} is the YARN application ID.
> {quote}
> If possible, it would be nice to have this in the [1.6 documentation|http://spark.apache.org/docs/1.6.0/monitoring.html#rest-api] as well.
