ERROR SafeScheduledExecutorService - Uncaught throwable from com.streamsets.pipeline.lib.executor.SafeScheduledExecutorService$SafeCallable@69717812: com.streamsets.datacollector.util.PipelineException: PREVIEW_0003 - Encountered error while previewing : java.security.AccessControlException: access denied ("java.io.FilePermission" "/opt/streamsets-datacollector-user-libs/test.js" "read") com.streamsets.datacollector.util.PipelineException: PREVIEW_0003 - Encountered error while previewing : java.security.AccessControlException: access denied ("java.io.FilePermission" "/opt/streamsets-datacollector-user-libs/test.js" "read")

Solution

As I've responded elsewhere, you will need to add a security policy to be able to load a script file. Add the following to $SDC_CONF/sdc-security.policy :

// Set global perm so that JS can load scripts from this directory
// Note - this means any code in the JVM can read this dir!
grant {
  permission java.io.FilePermission "/opt/streamsets-datacollector-user-libs/-", "read";
};

You will need to restart Data Collector for changes to the security policy file to take effect.
