> Nearly 10% (536 of 5789) of the tests run via `mvn verify` fail when any of
> the parent directories are protected against searches by others (i.e., do not
> include at least read/execute for others bits). This issue can be reproduced
> by changing permissions on a parent directory above target/testTemp such that
> public access is denied. For example, given a directory hierarchy of
> /opt/repos/apache/incubator-systemml, `chmod o-rw /opt/repos` removes from
> others the ability to access anything under /opt/repos. This will lead to
> the test's failure due to an IOException consisting of a stack caused by
> frame indicating the following:
> bq. Caused by: java.io.IOException: Resource
> file:/opt/repos/apache/incubator-systemml/target/testTemp/functions/recompile/CSVReadUnknownSizeTest/csv_read_unknown/scratch_space/_p1140_192.168.10.115/TmpOutput6/part-00000
> is not publicly accessable and as such cannot be part of the public cache.
> (A simple command to reproduce this is `mvn test -e
> -Dtest=CSVReadUnknownSizeTest`.)
> In enterprise settings, where a different department is responsible for the
> security of resources, it would be helpful if the target/testTemp directory
> could be configurable via a runtime parameter. This would allow enterprises
> to direct the tests to write to a truly temporary location where the
> restrictions against "others" is not a requirement.
