@arunmahadevan There are several incompatibilities. Most of them don't
matter because this is a part of the 1.x release, so rolling upgrades/etc will
not be possible.
The one incompatibility that remains is that you cannot use a pre 1.x kafka
spout on a 1.x cluster. It is always good practice to maintain the versions
the same, but in this case it is required.
KafkaUtils.generateTuples, calls the modified MultScheme.deserialize API
making this a problem.
> Fix Kafka spout to maintain backward compatibility to pass byte[] instead of
> ByteBuffer

> STORM-1220 introduced some changes where in one place it passes ByteBuffer as
> is instead of byte[]. Existing bolts that expects a byte[] fails due to this
> with "java.lang.RuntimeException: java.lang.ClassCastException:
> java.nio.HeapByteBuffer cannot be cast to [B "
