Sean Owen updated SPARK-25261:
------------------------------
Target Version/s: 3.0.0
Component/s: (was: Documentation)
YARN
Spark Core
Kubernetes
Summary: Standardize the default units of
spark.driver|executor.memory (was: Update configuration.md, correct the
default units of spark.driver|executor.memory)
Really, these properties are parsed differently in different parts of the code,
unfortunately. YARN and K8S parse a string without units as MiB, but not
spark-submit.
We can fix the docs in the first PR, and then in Spark 3, correct this behavior
inconsistency. I would even vote for no longer supporting unit-less strings in
any such property, then.

> Issue Type: Improvement
> Components: Kubernetes, Spark Core, YARN

> Reporter: huangtengfei
> Priority: Minor
>
> From
> [SparkContext|https://github.com/ivoson/spark/blob/master/core/src/main/scala/org/apache/spark/SparkContext.scala#L464]
> and
> [SparkSubmitCommandBuilder|https://github.com/ivoson/spark/blob/master/launcher/src/main/java/org/apache/spark/launcher/SparkSubmitCommandBuilder.java#L265]，we
> can see that spark.driver.memory and spark.executor.memory are parsed as
> bytes if no units specified. But in the doc, they are described as mb in
> default, which may lead to some misunderstanding.
