-------------------------------
Summary: When the number of partitions is greater than 2^28, it
will result in an error result
Key: SPARK-23358
URL: https://issues.apache.org/jira/browse/SPARK-23358
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 2.4.0
Reporter: liuxian
In the `checkIndexAndDataFile`,the `blocks` is the ` Int` type, when it is
greater than 2^28, `blocks*8` will overflow, and this will result in an error
result.
In fact, `blocks` is actually the number of partitions.
