             Summary: [CORE] Restore previous "os.arch" property in test suites after forcing to set specific value to "os.arch" property
                 Key: SPARK-12311
                 URL: https://issues.apache.org/jira/browse/SPARK-12311
             Project: Spark
          Issue Type: Bug
          Components: Spark Core
    Affects Versions: 1.5.2
            Reporter: Kazuaki Ishizaki
            Priority: Minor


Although current BlockManagerSuite.scala and SizeEstimatorSuite.scala set the specific value (e.g. "amd64") into system property "os.arch", they do not restore the original value of "os.arch" after these test suites. This may lead to failures in test cases that depends on architecture on other platform rather than amd64.
They should save the original value of "os.arch" and restore this at the end of these test suites.
