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.
> Standardize fall-back value of test.build.data for testing directories

> 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.
