The native hadoop libs have been packaged with AMS at, /usr/lib/ams-hbase/lib/hadoop-native
including SNAPPY. This should be set as -Djava.library.path=/usr/lib/ams-hbase/lib/hadoop-native/,
for the HMaster process.

1. What is the version of the Hadoop stack that is deployed?
2. What is the result of this operation on SLES: "which hadoop"?

Would one of you like to open a Jira for this?

Best Regards,

I am having this issue as well.  Is this a build or an environment problem?

Any additional steps needed for snappy beyond installing snappy and
Environment is sles11sp1 using trunk with AMS embedded mode.
