> 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.
