Sean Owen commented on SPARK-1527:
----------------------------------
If the paths are only used locally, then an absolute path never hurts (except
to be a bit longer). I assume that since these are references to a temp
directory that is by definition only valid locally, that absolute path is the
right thing to use.
In other cases, similar logic may apply. I could imagine in some cases the
right thing to do is transmit a relative path.
> rootDirs in DiskBlockManagerSuite doesn't get full path from rootDir0,
> rootDir1

> Key: SPARK-1527
> URL: https://issues.apache.org/jira/browse/SPARK-1527
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 0.9.0
> Reporter: Ye Xianjin
> Priority: Minor
> Labels: starter
> Original Estimate: 24h
> Remaining Estimate: 24h
>
> In core/src/test/scala/org/apache/storage/DiskBlockManagerSuite.scala
> val rootDir0 = Files.createTempDir()
> rootDir0.deleteOnExit()
> val rootDir1 = Files.createTempDir()
> rootDir1.deleteOnExit()
> val rootDirs = rootDir0.getName + "," + rootDir1.getName
> rootDir0 and rootDir1 are in system's temporary directory.
> rootDir0.getName will not get the full path of the directory but the last
> component of the directory. When passing to DiskBlockManage constructor, the
> DiskBlockerManger creates directories in pwd not the temporary directory.
> rootDir0.toString will fix this issue.
