Parquet-tools cat mangles strings created by other clients

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:
```

hadoop jar parquet-tools-1.9.1-SNAPSHOT.jar meta /parquet-r-00000
```
Output:
```

file: hdfs:///parquet-r-00000
creator: parquet-mr version 1.8.1 (build 4aba4dae7bb0d4edbcf7923ae1339f28fd3f7fcf)

file schema: MY_DATA
--------------------------------------------------------------------------------
myfield: OPTIONAL BINARY R:0 D:1

row group 1: RC:37343 TS:32397576 OFFSET:4
--------------------------------------------------------------------------------
myfield: BINARY SNAPPY DO:0 FPO:4 SZ:273374/556406/2.04 VC:37343 ENC:RLE,BIT_PACKED,PLAIN_DICTIONARY ST:[no stats for this column]
```
 Has anyone seen this before?

Beginne mit dem parquet-tools cat-Pfad und den Metadaten für das im Bericht beschriebene Feld OPTIONAL BINARY und vergleiche dann dessen Ausgabe mit den von Pig und Spark gelesenen Strings. Reproduziere die Verfälschung anhand einer vom Java-MR-Prozess erstellten Parquet-Datei; abgeschlossen ist die Aufgabe, wenn parquet-tools cat diese String-Felder korrekt anzeigt.
