column chunk page write store log message displays incorrect information

It is printing the size of the dictionary (in terms of the number of keys) twice and calling the second time the 'compressed byte count'. An accurate account of that number would be very helpful for accounting for disk space usage. The actual 'compressed byte count' is indeed calculated at a point near there so I am guessing this is a simple mistake.

Öffne parquet-hadoop/src/main/java/parquet/hadoop/ColumnChunkPageWriteStore.java an der referenzierten Zeile und untersuche die nahegelegene Logmeldung sowie die Berechnung der Anzahl komprimierter Bytes. Erledigt ist es, wenn das Store-Log die tatsächliche Anzahl komprimierter Bytes meldet, statt die Größe des Wörterbuchs zweimal auszugeben.
