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.

参照されている行の parquet-hadoop/src/main/java/parquet/hadoop/ColumnChunkPageWriteStore.java を開き、近くにあるログメッセージと圧縮バイト数の計算を確認してください。完了条件は、store のログが辞書サイズを2回出力するのではなく、実際の圧縮バイト数を報告することです。
