-C++ code with pipes and CLapack Libraries
Salman Toor 2013-11-15, 17:54
I am trying to run my C++ code using hadoop-1.2.1. I am using pipes. The code requires to access CLAPACK libraries. My test setup is based on single node. CLAPECK is installed on that node. Everything compiles without any problem but the when I run a job the maper hangs first and than failed. In the log files, there is no error messages. The only message I can see is
org.apache.hadoop.mapred.Tesk: Communication exception: org.api.ipc.RemoteException: java.io.IOException: JvmValidate Failed. Ignoring request from task
Without CLAPACK everything works fine.
I have also set the LD_LIBRARY_PATH in my application.xml file
But no effect. Can some please give me some hint or redirect me to some link where I can learn how to use external libraries.
