Subject How to set java.library.path in a spark cluster
Date Wed, 10 Sep 2014 04:14:17 GMT
Hi,

I am working on a 3 machine cloudera cluster. Whenever I submit a spark job
as a jar file with native dependency on mosek it shows the following error.

java.lang.UnsatisfiedLinkError: no mosekjava7_0 in java.library.path

How should I set the java.library.path. I printed the environment variable
and it shows;
-Djava.library.path= -Xms512m -Xmx512m,

I added the following lines to the spark-env.sh file but it was of no help.
The path contains both the mosek.jar and the libmosek_7.0.so files.

export
SPARK_LIBRARY_PATH=${SPARK_HOME}/lib:/home/chanda/mosek/7/tools/platform/linux64x86/bin
export
SPARK_MASTER_OPTS='-Djava.library.path="/home/chanda/mosek/7/tools/platform/linux64x86/bin'
export
SPARK_WORKER_OPTS='/home/chanda/mosek/7/tools/platform/linux64x86/bin'
export
SPARK_HISTORY_OPTS='/home/chanda/mosek/7/tools/platform/linux64x86/bin'
export
SPARK_DAEMON_JAVA_OPTS='/home/chanda/mosek/7/tools/platform/linux64x86/bin'

Please help
