 Summary: [Java] Remove Netty references from ArrowBuf and move 
Allocator out of vector package
 Key: ARROW-4526
 URL: https://issues.apache.org/jira/browse/ARROW-4526
 Project: Apache Arrow
  Issue Type: New Feature
Reporter: Jacques Nadeau


Arrow currently has a hard dependency on Netty and exposes this in public APIs. 
This shouldn't be the case. There could be many allocator implementations with 
Netty as one possible option. We should remove hard dependency between 
arrow-vector and Netty, instead creating a trivial allocator. ArrowBuf should 
probably expose an  T unwrap(Class clazz) method instead to allow inner 
providers availability without a hard reference. This should also include 
drastically reducing the number of methods on ArrowBuf as right now it includes 
every method from ByteBuf but many of those are not very useful, appropriate.

This work should come after we do the simpler ARROW-3191

We need to enable conversion from ArrowError to ParquetError. This is useful 
when integrating arrow with parquet, e.g. when reading parquet data into arrow.
