I have some parquet files that are created by Java MR process (which I do not
own). I am able to read these fields successfully in pig and Spark, but for
some reason the String fields are being mangled when I view the files with
parquet-tools (cat).
Here are the details on the file metadata using today's build of parquet-tools:
{noformat}
hadoop jar parquet-tools-1.9.1-SNAPSHOT.jar meta <hdfs>/parquet-r-00000
{noformat}
Output:
{noformat}
file: hdfs://<path>/parquet-r-00000
creator: parquet-mr version 1.8.1 (build
