> We added a new java interface to support parquet read and write from hdfs or local file.
> The purpose of this implementation is that when we loading and dumping parquet data in Java, we can only use rowBased put and get methods. Since arrow already has C++ implementation to load and dump parquet, so we wrapped those codes as Java APIs.
> After test, we noticed in our workload, performance improved more than 2x comparing with rowBased load and dump. So we want to contribute codes to arrow.
> since this is a total independent change, there is no codes change to current arrow codes. We added two folders as listed:  java/adapter/parquet and cpp/src/jni/parquet
