Subject How to get and save core dump of native library in executors
Date Thu, 12 May 2016 21:23:27 GMT
Hi

I am running my spark application with some third party native libraries .
but it crashes some time and show error " Failed to write core dump. Core
dumps have been disabled. To enable core dumping, try "ulimit -c unlimited"
before starting Java again " . 

Below are the log :

 A fatal error has been detected by the Java Runtime Environment:
