This looks somewhat similar to my Subtle Classloader Issue from
yesterday. I'll be watching this thread too.

Hello,
I'm using some JNI interfaces, via a R. My classpath contains all the
jar files in $HADOOP_HOME and $HADOOP_HOME/lib
My class is
public SeqKeyList() throws Exception {
config = new org.apache.hadoop.conf.Configuration();
config.addResource(new Path(System.getenv("HADOOP_CONF_DIR")
+"/hadoop-default.xml"));
config.addResource(new Path(System.getenv("HADOOP_CONF_DIR")
+"/hadoop-site.xml"));
System.out.println("C="+config);
filesystem = FileSystem.get(config);
System.out.println("C="+config+"F=" +filesystem);
System.out.println(filesystem.getUri().getScheme());
}
I am using a distributed filesystem
(org.apache.hadoop.hdfs.DistributedFileSystem for fs.hdfs.impl).
When run from the command line and this class is created everything works fine
When called using jni I get
java.lang.ClassNotFoundException: org.apache.hadoop.hdfs.DistributedFileSystem
Is this a jni issue? How can it work from the commandline using the
same classpath, yet throw this is exception when run via JNI?
