Hi,

I am setting up HDFS security with Kerberos:
When I manually started the first datanode, I got the following messages (the namenode is started):

1) INFO org.apache.hadoop.security.UserGroupInformation: Login successful for user ....
2) ERROR org.apache.hadoop.hdfs.server.datanode.DataNode: java.lang.RuntimeException: Cannot start secure cluster without privileged resources.

OS: Ubuntu 12.04
Hadoop: 1.0.4

It seems that it could login successfully but something is missing
Please help!

Thanks

 

Secure DN needs to be started as root (it runs as proper user, but
needs to be started as root to grab reserved ports), and needs a
proper jsvc binary (for your arch/OS) available. Are you using
tarballs or packages (and if packages, are they from Bigtop)?

Hi,

A question:
I started Secure DN then ran JPS as root, I could not find any running DN:
16152
16195 Jps

However, when I tried to start the secure DN again, I got:
Warning: $HADOOP_HOME is deprecated.
datanode running as process 16117. Stop it first.

Does it mean JPS is no longer a tool to check DN in secure mode?

Thanks

The 16152 should be the DN JVM I think. This is a jps limitation, as
seen at http://docs.oracle.com/javase/1.5.0/docs/tooldocs/share/jps.html
and jsvc (which secure mode DN uses) is such a custom launcher.

"The jps command uses the java launcher to find the class name and
arguments passed to the main method. If the target JVM is started with
a custom launcher, the class name (or JAR file name) and the arguments
to the main method will not be available. In this case, the jps
command will output the string Unknownfor the class name or JAR file
name and for the arguments to the main method."

Hi,

Thanks for your reply.

However, I think 16152 should not be the DN, since
1) my second try of "/usr/local/hadoop/bin/hadoop-daemon.sh start datanode" says 16117 (i.e. I ran start datanode twice), and
2) ps axu | grep 16117, I got
root     16117  0.0  0.0  17004   904 pts/2    S    21:34   0:00 jsvc.exec -Dproc_datanode -outfile /usr/local/hadoop-1.0.4/libexec/ ...

These are the two reasons that I think JPS is no longer a tool to check secure DN.

Thanks again!

Could you also check what 16152 is? The jsvc is a launcher process,
not the JVM itself.

As I mentioned, JPS is pretty reliable, just wont' show the name of
the JVM launched by a custom wrapper - and will show just PID.
