Eric Liang 44c7c62bcf [SPARK-16021] Fill freed memory in test to help catch correctness bugs ... ## What changes were proposed in this pull request? This patches `MemoryAllocator` to fill clean and freed memory with known byte values, similar to https://github.com/jemalloc/jemalloc/wiki/Use-Case:-Find-a-memory-corruption-bug . Memory filling is flag-enabled in test only by default. ## How was this patch tested? Unit test that it's on in test. cc sameeragarwal Author: Eric Liang <ekl@databricks.com> Closes #13983 from ericl/spark-16021.		2016-07-06 16:30:25 -07:00
