After {code} mvn install -Dsnappy.prefix=(absolute-path to Snappy) {code}, I get the following error:

I'm aware that this issue is similar to what Stack experienced (03/Jun/11 03:29), so I've tried everything that you and others at p/hadoop-snappy suggested. However, my Hadoop-Snapppy is the latest subversion, and my problem persists ever after I replaced {code:xml} LDFLAGS=$ldflags_bak {code} with {code:xml} #LDFLAGS=$ldflags_bak {code}.

Unlike many experts like you and others in JIRA, I'm an undergraduate who just got into the world of Hadoop and HBase, and therefore does not have extensive knowledge of what goes on in background. I'd really appreciate if you could help me with this issue.

> (This JIRA builds on HBASE-3691)
> I'm working on simplifying how to use Hadoop Snappy from other based maven projects. The idea is that hadoop-snappy JAR and the SOs (snappy and hadoop-snappy) would be picked up from a Maven repository (like any other dependencies). SO files will be picked up based on the architecture where the build is running (32 or 64 bits).
> For Hbase this would remove the need to manually copy snappy JAR and SOs (snappy and hadoop-snappy) into HADOOP_HOME/lib or HBASE_HOME/lib and hadoop-snappy would be handled as a regular maven dependency (with a trick for the SOs file).
> The changes would affect only the pom.xml and the would be in a 'snappy' profile, thus requiring '-Dsnappy' option in Maven invocations to trigger the including of snappy JAR and SOs.
> Because hadoop-snappy (JAR and SOs) are not currently avail in public Maven repos, until that happens, Hbase developer would have to checkout and 'mvn install' hadoop-snappy. Which is (IMO) simpler than what will have to be done in once HBASE-3691 is committed.
