Subject [jira] Commented: (HADOOP-5916) Standardize fall-back value of test.build.data for testing directories
Date Tue, 26 May 2009 23:19:45 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-5916?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12713323#action_12713323
] 

Hong Tang commented on HADOOP-5916:
-----------------------------------

No strong opinion either ways (/tmp or build/test/data). But a quick comment on the following:

bq. Right now it is simply impossible to run some tests from eclipse because they try to write
to "/tmp" or "." and this collides with the data already stored there.

I think it is possible to explicitly set it as JVM parameters through -Dtest.build.data=XXX.

> 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.
