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.

Ouvrez parquet-hadoop/src/main/java/parquet/hadoop/ColumnChunkPageWriteStore.java à la ligne référencée et examinez le message de log voisin ainsi que le calcul du nombre d’octets compressés. C’est terminé lorsque le log du store indique le nombre réel d’octets compressés au lieu d’imprimer deux fois la taille du dictionnaire.
