Wellington Chevreuil commented on HBASE-22393:
----------------------------------------------
Latest patch is relocating references to any class in *javax* domain, so it
causes *NoClassDefFoundError* on process loading the generated hboss jar:
{noformat}
Exception in thread "main" java.lang.NoClassDefFoundError:

Since the offending dependency (jsr305) is already marked for exclusion, I
believe we can safely remove this *javax relocation rule* from shade section in
the pom. Attaching a patch example that worked on my tests (notice I don't have
*javax* on the relocations portion).
> HBOSS: Shade curator to prevent conflict with Hadoop

> Key: HBASE-22393
> URL: https://issues.apache.org/jira/browse/HBASE-22393
> Project: HBase
> Issue Type: Bug
> Components: Filesystem Integration
> Affects Versions: hbase-filesystem-1.0.0-alpha1
> Reporter: Sean Mackrory
> Assignee: Sean Mackrory
> Priority: Critical
> Labels: HBOSS
> Fix For: hbase-filesystem-1.0.0-alpha1

> Attachments:

> Hadoop uses a very old version of Curator, and if it ever ends up in the
> classpath with HBOSS you can get this:
> {code}Exception in thread "main" java.lang.IllegalAccessError: tried to
> access method
> org.apache.curator.framework.recipes.locks.InterProcessMutex.isOwnedByCurrentThread()Z
> from class org.apache.hadoop.hbase.oss.sync.ZKTreeLockManager{code}
> I think the simplest solution is to just shade Curator.
