-------------------------------------------

Thanks for the patch [~tmarquardt]. Patch lgtm (non-binding).  I tried out the patch on multi-node
cluster and it works fine.

> On certain conditions, BlockBlobInputStream can throw IndexOutOfBoundsException. Following
is an example
> {{length:297898, offset:4194304, buf.len:4492202, writePos:4194304}} : 
> In this case, {{MemoryOutputStream::capacity()}} would end up returning negative value
and can cause {{IndexOutOfBoundsException}}
> It should be {{return buffer.length - offset;}} to determine current capacity.
