-------------------------------------
Summary: Spark resources - user configs change .count to be
.amount, and yarn configs should match
Key: SPARK-27760
URL: https://issues.apache.org/jira/browse/SPARK-27760
Project: Spark
Issue Type: Story
Components: Spark Core
Affects Versions: 3.0.0
Reporter: Thomas Graves
For the Spark resources, we created the config
spark.\{driver/executor}.resource.\{resourceName}.count
I think we should change .count to be .amount. That more easily allows users to
specify things with suffix like memory in a single config and they can combine
the value and unit. Without this they would have to specify 2 separate configs
which seems more of a hassle for the user.
Spark on yarn already had added configs to request resources via the configs
spark.yarn.\{executor/driver/am}.resource=<some amount>, where the <some amont>
is value and unit together. We should change those configs to have a .amount
suffix on them to match the spark configs and to allow future configs to be
more easily added. YARN itself already supports tags and attributes so if we
want the user to be able to pass those from spark at some point having a suffix
makes sense.
