Anoop Sam John commented on HBASE-17239:
----------------------------------------

bq.static CodedInputStream newInstance(ByteInput buf, boolean 
bufferIsImmutable) {
This method is not really useful now.  Just remove it?  Can fix on commit.  U 
will have to remove from 2 files in patch.

> Add UnsafeByteOperations#wrap(ByteInput, int offset, int len) API

> Instead of exposing the newInstance(ByteInput, boolean) in CIS we could just 
> add a UnsafeByteOperations#wrap(ByteInput, offset, len). And we could just 
> call that and do a #newcodedInput() over that. So internally we do return a 
> immutable version of the ByteInput only. This way we can avoid 
> CIS#newInstance(ByteInput) exposure and can keep it package private as done 
> in COS.
