[SPARK-20280][CORE] FileStatusCache Weigher integer overflow ## What changes were proposed in this pull request? Weigher.weigh needs to return Int but it is possible for an Array[FileStatus] to have size > Int.maxValue. To avoid this, the size is scaled down by a factor of 32. The maximumWeight of the cache is also scaled down by the same factor. ## How was this patch tested? New test in FileIndexSuite You can merge this pull request into a Git repository by running: $ git pull https://github.com/bogdanrdc/spark SPARK-20280 Alternatively you can review and apply these changes as the patch at: https://github.com/apache/spark/pull/17591.patch To close this pull request, make a commit to your master/trunk branch with (at least) the following in the commit message: This closes #17591 ---- commit f4ae52a0c60b9d2a086e4f1ad0bb3675bebc47da Author: Bogdan Raducanu <bog...@databricks.com> Date: 2017-04-10T11:52:41Z fix + test ---- --- If your project is set up for it, you can reply to this email and have your reply appear on GitHub as well.
