Pavan Kumar commented on GIRAPH-915:
------------------------------------
throwing an exception sounds better.
this is because we can have future implementations of bytedatastructs and
available is really needed (for example in bytebufdatainput, etc.)
> With BigDataIO some messages can get ignored

> ExtendedDataInput has "int available()" method, and when iterating through
> messages we check if it's grater then zero. For BigDataIO we can get an
> overflow here, returning a negative values and ignoring the rest of messages.
