Hi, I think I have found the cause of the tests failing. I have two disks on my laptop. The spark project dir is on an HDD disk while the tempdir created by google.io.Files.createTempDir is the /var/folders/5q/.... ,which is on the system disk, an SSD. The ExecutorLoaderSuite test uses org.apache.spark.TestUtils.createdCompiledClass methods. The createCompiledClass method first generates the compiled class in the pwd(spark/repl), thens use renameTo to move the file. The renameTo method fails because the dest file is in a different filesystem than the source file.
I modify the TestUtils.scala to first copy the file to dest then delete the original file. The tests go smoothly. Should I issue an jira about this problem? Then I can send a pr on Github. -- Ye Xianjin Sent with Sparrow (http://www.sparrowmailapp.com/?sig) On Tuesday, April 15, 2014 at 3:43 AM, Ye Xianjin wrote: > well.
