Usage

From source file:azkaban.jobtype.connectors.teradata.TeraDataWalletInitializer.java

/**
 * As of TDCH 1.4.1, integration with Teradata wallet only works with hadoop jar command line command.
 * This is mainly because TDCH depends on the behavior of hadoop jar command line which extracts jar file
 * into hadoop tmp folder.//from   w w w  . j a v  a  2  s  .c om
 *
 * This method will extract tdchJarfile and place it into temporary folder, and also add jvm shutdown hook
 * to delete the directory when JVM shuts down.
 * @param tdchJarFile TDCH jar file.
