Sylvain Lebresne updated CASSANDRA-2994:
----------------------------------------
Attachment: 2994.patch
A probable cause is that snappy doesn't seem to guarantee that the compressed
output will shorter or equal to the input (indeed,
Snappy.maxCompressedLength(65536) == 76490).
Attaching fix for that. I don't see what else it can be actually, but I don't
know how to reproduce, so Stu, if you can reproduce and can check if this fixes
it, that'd be cool.
