Subject [jira] [Commented] (SPARK-12311) [CORE] Restore previous value of "os.arch" property in test suites after forcing to set specific value to "os.arch" property
Date Mon, 14 Dec 2015 17:23:46 GMT

    [ https://issues.apache.org/jira/browse/SPARK-12311?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15056317#comment-15056317
] 

Kazuaki Ishizaki commented on SPARK-12311:
------------------------------------------

Yes. Even when I run core test on a ppc64le machine, I got "amd64" from System.getProperty("os.arch")
in another test suite (e.g. StorageStatusListnerSuite that is lately executed).
Although this mismatch does not seem to cause any test failure now, this would lead to a test
failure in the future.

> 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 a test case 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.
