Method Detail

addSQLite4JavaNativeLibsToDC

public static void addSQLite4JavaNativeLibsToDC(org.apache.hadoop.conf.Configuration conf)
                                         throws java.io.IOException,
                                                java.net.URISyntaxException

Adds the SQLite native libraries to the DistributedCache so that they will be present in the java.library.path of the child's Hadoop task.

Usually you don't need to do this as the task will already try to load them from the job's uncompressed JAR, however it is not assured that all Hadoop versions do the uncompressing of the JAR so in this case it's safer to use this.

This method uses the default "native" folder.

Throws:

java.io.IOException

java.net.URISyntaxException
