We are still running with assertions on in tests, and this block is failing the assertion. Seems important:
{code}
if (data instanceof HFileBlock) {
ByteBuffer sliceBuf = ((HFileBlock) data).getBufferReadOnlyWithHeader();
sliceBuf.rewind();
assert len == sliceBuf.limit() + HFileBlock.EXTRA_SERIALIZATION_SPACE;
{code}
