Ryan Blue commented on AVRO-1846:
---------------------------------
[~jocoda], thanks for reporting this. It looks like the problem is happening
while you're initializing a long data field, which is probably field 1 in
record "event". Is that record defined by your code? I'm wondering if you could
get around this by changing your schema so that the long fields appeared first.
Otherwise, the solution is to add an alignment flag that inserts bytes in the
in-memory structure, right?
