Description

I download sources from release/1.11.0 and built.
https://github.com/apache/parquet-mr/releases/tag/apache-parquet-1.11.0

As I ran cat command of parquet-tools, the below exception occurred.

java -jar ./parquet-tools-1.11.0.jar cat D:\development\repository\git\parquet-column-index-benchmark\src\test\res ources\v11.parquet
java.lang.ClassCastException: required int32 int32_field is not a group

The schema of v11.parquet is below:

java -jar ./parquet-tools-1.11.0.jar schema D:\development\repository\git\parquet-column-index-benchmark\src\test\ resources\v11.parquet
message test {
  required int32 int32_field;
  required int64 int64_field;
  required float float_field;
  required double double_field;
  required binary binary_field;
  required int64 timestamp_field (TIMESTAMP(MILLIS,true));
}
