[jira] Commented: (HADOOP-5916) Standardize fall-back value of test.build.data for testing directories

["Eli Collins (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HADOOP-5916?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12792554#action_12792554 ] 

Eli Collins commented on HADOOP-5916:
-------------------------------------

I think the issue here is whether the path is absolute. Is there a way to have $PROJ_HOME/build/test/data so the default value is an absolute path? Leaving it just build/test/data means eg in TestLocalFSFileContextMainOperations it tries to use /user/eli/build/test/data which doesn't make sense since it's a local fs.

> Currently when the test.build.data property is not set, as happens when run through some configurations of Eclipse, the fall-back value varies wildly.  Most calls set to /tmp, which is not good as it is beyond the scope of the ant clean task and thus will not be deleted.  Others default to "." which can drop the test files right in the current directory.  Speaking with Konstanin, it seems the correct location should be "build/test/data" to ensure any files that are created are within the scope of Ant's clean command.
> Attached is the current variation in this setting.
