wgtmac commented on PR #1000:
URL: https://github.com/apache/parquet-mr/pull/1000#issuecomment-1282105001

   > Yep, we test encryption interop using binary files in the parquet-testing 
repo. @wgtmac Please have a look at this code: 
https://github.com/apache/parquet-mr/blob/master/parquet-hadoop/src/test/java/org/apache/parquet/hadoop/TestEncryptionOptions.java#L130
   
   @ggershinsky @emkornfield  Yes I did that in the previous commit: 
https://github.com/apache/parquet-mr/pull/1000/commits/6e02cb20eb580e80a793b02d187237770868b335#diff-61de8043597197e5da4b42ebfe2d123b9c42e56fcb520e293c1a10ba55fa93cc
 but switched to local file to avoid unstable test.
   
   @shangxinli Should I keep the resource file approach or switch to the 
download approach?

> There is a long history about the LZ4 interoperability of parquet files 
> between parquet-mr and parquet-cpp (which is now in the Apache Arrow). 
> Attached links are the evidence. In short, a new LZ4_RAW codec type has been 
> introduced since parquet format v2.9.0. However, only parquet-cpp supports 
> LZ4_RAW. The parquet-mr library still uses the old Hadoop-provided LZ4 codec 
> and cannot read parquet files with LZ4_RAW.
