I want to see contents of a parquet
file. I ran the following command but got error java.lang.ClassCastException: optional int32 count is not a group
.
manu@manu-VirtualBox:~/parquet-mr/parquet-tools/target$ java -jar parquet-tools-1.12.0-SNAPSHOT.jar cat ~/test/part-00000-3d55da69-71e8-462f-a478-68363b7af1a1-c000.snappy.parquet
What might be the issue?
Update your parquet-mr. This is the result of a bug, PARQUET-1527, which is already fixed both in the master branch on github and in the latest release candidate for 1.11.0.
