Isabel Drost-Fromm commented on MAHOUT-1325:
--------------------------------------------
I just did a
chmod 000 /tmp/hadoop-$USER
mvn clean install
found another test that tries to write there in core
ParallelALSFactorizationJobTest.recommenderJobWithIDMapping:359
By the way although MAPREDUCE-5367 is clearly related I think given that we
use Maven as build tool having our build write stuff anywhere except in the
target directories (which on mvn clean get purged automatically) isn't a
particularly good practice and should be fixed in the long run. I'd really like
to see a solution that makes the build fail if any of our code tries that (much
like we fail fast when users try to build our project with anything older than
Maven 3).
