Hi, I am trying to run a JNI application on StandAlone mode and I have been
getting this result ever since.
I've looked up every possible webs and sites but never could get the
solution to it.
Please help me find out what's wrong.

I have 2 java files (LangAnal.java, freeparser.java)
LangAnal.java belongs to a package "org.etri.mp2893"
freeparser.java belongs to a package "org.knu.freeparser"

freeparser.java loads "libetri_lmi.so" which is in "/home/qa/lang/dll4jni/"
and I believe "libetri_lmi.so" uses another library "libparser.so" which is
in "/home/qa/lang/lib".

I have compiled LangAnal.java and freeparser.java. The resulting classes are
placed respectively at "/home/qa/lang/dll4jni/org/etri/mp2893/" and
"/home/qa/lang/dll4jni/org/knu/freeparser/".

Then I have archived those classes by

"jar -cvef org.etri.mp2893.LangAnal ./LangAnal.jar ./org/*"

from the directory of "/home/qa/lang/dll4jni/".

Then I tried to run

hadoop jar LangAnal.jar ./news.txt ./output

from the same directory and I get the result down below.

I tried to set LD_LIBRARY_PATH to
".:/home/qa/lang/dll4jni:/home/qa/lang/lib"
I tried java.setProperty("java.library.path", "/home/qa/lang/dll4jni"); in
freeparser.java.
So far nothing has worked.

But the funny thing is, if I run

hadoop -Djava.library.path=/home/qa/lang/dll4jni org.etri.mp2893.LangAnal
./news.txt ./output

from "/home/qa/lang/dll4jni/" it works just fine. So I guess the problem is
just about jar file.
And I intend to run this application in Fully-Distributed mode soon, I have
to figure out how to run jar files.

Please someone help me.

Try

   1. export JAVA_LIBRARY_PATH=/home/qa/lang/dll4jni/
   2. mkdir lib; mv LangAnal.jar lib; jar -cvef org.etri.mp2893.LangAnal
   ./lib ./org

In a distributed mode you'll have to copy your dynamic libs to some
directory thoughout the cluster and point JAVA_LIBRARY_PATH to it (or you
can use distributed cache).

Let me know if you have other config problems.

Alex,

Thanks for your advice.
I tried both of them and neither works.
I am still getting the UnsatisfiedLinkError when I try to run my application
in StandAlone mode.

I also made LangAnal.java belong to the package of "org.knu.freeparser" just
in case. But still no luck.
I put libetri_lmi.so to "/usr/lib" and still no luck.

Edward,

If it's an option to copy the libraries to a fixed location on all the
cluster nodes, you could do that and configure them in the library
path via mapred.child.java.opts. Please look at http://bit.ly/ab93Z8
(MapReduce tutorial on Hadoop site) to see how to use this config
option for setting paths to native libraries.

Thanks
Hemanth

Hi Edward,  Can you provide the output of 'ps -aef -u hadoop | grep Child'
on a tasktracker node while your job is running? -- Alex K

Hi Alex,
I haven't even succeded running jobs on standalone mode yet. I will  
post the result of your "ps -aef" command as soon as I can get my job  
running on fully distributed mode though.  Thanks for the support.
