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.

打开 parquet-hadoop/src/main/java/parquet/hadoop/ColumnChunkPageWriteStore.java 中所引用的行，并检查附近的日志消息和压缩字节数计算。完成的标准是，store 日志报告实际的压缩字节数，而不是将字典大小打印两次。
