Michael Noll commented on PIG-3159:
-----------------------------------
FWIW the original problem seems to be the Snappy bug report discussed at:
* [Native (Snappy) library loading fails on openjdk7u4 for
mac|https://github.com/xerial/snappy-java/issues/6]
This bug is already fixed in the latest Snappy-Java 1.5 milestone releases.
Regarding Pig: I tried to grep the Pig sources (trunk) for snappy version
information. The only good hit was {{lib/jdiff/pig_0.11.1.xml}}, which lists
{{/root/.ivy2/cache/org.xerial.snappy/snappy-java/bundles/snappy-java-1.0.3.2.jar}}.
However I found no occurrence of Snappy actually being listed as a build
dependency for Pig, which indicates to me that Pig is not bundling Snappy at
all but rather requires the user to make sure the snappy jar/native lib are
available on Pig's {{CLASSPATH}} when a Pig script is run.
@Bill: Maybe you can also try to verify whether using Snappy 1.5.x together
with Pig and JDK7 will work on your Mac?
