      When running in CDAP Standalone, the Cask Hydrator plugin NaiveBayesTrainer has a *permgen* memory leak that leads to an out-of-memory error if the plugin is repeatedly used a number of times, as few as six runs. The only workaround is to reset the memory by restarting the CDAP Standalone.

      Description

      NaiveBayesTrainer has a permgen leak. This results in permgen out of memory error in CDAP SDK, if you run it a few times. I was able to trigger failure by running it ~6 times.

      This requires a restart of the CDAP SDK in order to reset the memory and to be functional again.
