Snappy-java fails on Mac OS JDK 1.7 about carmine HOT 10 CLOSED

Just wanted to summarize for others needing this workaround:

1. If you don't already have it, get the Snappy jar file from http://code.google.com/p/snappy-java/downloads/list
2. Extract the jar somewhere (it's just a zip file).
3. In org/xerial/snappy/native/Mac/ you'll find i386 (32bit) and x86_64 (64bit) .jnilib files. Copy the appropriate one to your project's root path (where your project.clj is).

And you should be good to go!

Hi Rob,

Thanks for bringing this forward!

Okay - it turns out this is a path bug with Snappy 1.0.4.1 affecting Java 7 on OSX: http://code.google.com/p/snappy-java/issues/detail?id=39

Snappy is generally well supported; this is an unusual issue because of a naming-convention change in JDK7. Since it's a simple bug to fix, and since Snappy is so widely used - I'm hoping they'll get around to fixing it soon. EDIT: I see they've already marked it for inclusion in 1.0.5.

In the meantime, you should be able to manually extract the relevant JNI from your snappy-java-1.0.4.1.jar and put it in your project's root path. Alternatively you could fiddle with the path options described here: http://code.google.com/p/snappy-java/source/browse/src/main/java/org/xerial/snappy/SnappyLoader.java?name=snappy-java-1.0.3-rc4&r=d05ec05c669617273bde3ff34ae995e070b5844a&spec=svn25d8cadcff5ab995564a240431f7ab6933534722 although that seems like more effort and I didn't try it myself. (I did successfully try the extraction running OSX+JDK7).

I'll also look into alternatives ASAP though unfortunately last time I checked, the non-JNI Snappy ports weren't nearly as mature - so I'm hesitant to move in that direction unnecessarily.

At the very least, I'll make sure to document this so it doesn't bite anyone else!

Cheers!

Thank you very much for tracking this down! :)

Found this ticket while Googling, and it fixed my problem with Cassandra 1.x on OSX, so thanks! For the record, I had to put the jnilib file into Cassandra's root directory (i.e. $CASSANDRA_HOME), not the lib folder.

Heh heh- no problem: glad it was helpful :)

The root cause should be fixed now, waiting for a point release of Snappy Java.

Thanks, that's great. Will update Nippy soon as they release 1.0.5.

Okay, this is now resolved.

snappy-java-1.0.5-M2.jar works, just replace the older version under cassandra lib.

Yes, snappy 1.0.5 works just fine with JDK 7
