From 46fcb9e0dbb2b28110f68a3d9f6c0c47bfd197b1 Mon Sep 17 00:00:00 2001 From: Keiji Yoshida <yoshida.keiji.84@gmail.com> Date: Sat, 22 Aug 2015 02:38:10 -0700 Subject: [PATCH] Update programming-guide.md Update `lineLengths.persist();` to `lineLengths.persist(StorageLevel.MEMORY_ONLY());` because `JavaRDD#persist` needs a parameter of `StorageLevel`.

If we also wanted to use `lineLengths` again later, we could add: {% highlight java %} -lineLengths.persist(); +lineLengths.persist(StorageLevel.MEMORY_ONLY()); {% endhighlight %} before the `reduce`, which would cause `lineLengths` to be saved in memory after the first time it is computed. -- GitLab
