snappy golang compress and java uncompress don't work

[jazzmr]

I have a problem, golang compress and java uncompress, it don't work, what can I do with this problem

[tomwilkie]

I've reproduced this issue with a simple pair of programs: https://github.com/weaveworks-experiments/prometheus-benchmarks/tree/master/cmd/snappy

The output I get when encoding the string "hello world" in go is:

$ hexdump output
0000000 ff 06 00 00 73 4e 61 50 70 59 01 0f 00 00 00 7e
0000010 d8 6d 68 65 6c 6c 6f 20 77 6f 72 6c 64         
000001d

When I run the little java app, I get a java.io.IOException: FAILED_TO_UNCOMPRESS(5)

Okay problem seems to be golang/snappy's framing format is not compatible with xerial/snappy-java. If you use golang snappy.Encode then the data can be decoded by xerial.

Hi
I have data snappy compressed in java using org.xerial.snappy:snappy-java 1.1.7.2
I am trying to read in a golang service and decode it using github.com/eapache/go-xerial-snappy snappy.Decode
I am getting "malformed xerial framing"

Kindly note data is compressed properly as we have a live java service using it.
Kindly let me know how we can resolve this or this is not recommended and I will need to compress it using golang snappy. But it is an overhead for us.
