liuxian created SPARK-27256:
-------------------------------
Summary: If the configuration is used to set the number of bytes,
we'd better use `bytesConf`'.
Key: SPARK-27256
URL: https://issues.apache.org/jira/browse/SPARK-27256
Project: Spark
Issue Type: Improvement
Components: Spark Core, SQL
Affects Versions: 3.0.0
Reporter: liuxian
Currently, if we want to configure `spark. sql. files. maxPartitionBytes` to
256 megabytes, we must set `spark. sql. files. maxPartitionBytes=268435456`,
which is very unfriendly to users.
And if we set it like this:`spark. sql. files. maxPartitionBytes=256M`, we will
encounter this exception:
_Exception in thread "main" java.lang.IllegalArgumentException:
spark.sql.files.maxPartitionBytes should be long, but was 128M_
_at
org.apache.spark.internal.config.ConfigHelpers$.toNumber(ConfigBuilder.scala:34)_
