ColumnChunkPageWriter uses only heap memory.

After PARQUET-160 was resolved, ColumnChunkPageWriter started using ConcatenatingByteArrayCollector. There are all data is collected in the List of byte[], before writing the page. No way to use direct memory for allocating buffers. ByteBufferAllocator is present in the [ColumnChunkPageWriter](https://github.com/apache/parquet-mr/blob/master/parquet-hadoop/src/main/java/org/apache/parquet/hadoop/ColumnChunkPageWriteStore.java#L73) class, but never used.

Using of java heap space in some cases can cause OOM exceptions or GC's overhead.
ByteBufferAllocator should be used in the ConcatenatingByteArrayCollector or OutputStream classes.

Inizia da parquet-hadoop/src/main/java/org/apache/parquet/hadoop/ColumnChunkPageWriteStore.java e segui come ColumnChunkPageWriter passa il proprio ByteBufferAllocator a ConcatenatingByteArrayCollector o all’OutputStream pertinente. Verifica dove vengono accumulati i dati delle pagine prima della scrittura e determina se il percorso completo alloca tramite l’allocator fornito invece di usare esclusivamente array di byte nell’heap.
