> Right now this is expressed as failed Precommit-YARN-build jobs when they run on H5 / H6 (see INFRA-13148), but the problem exists for all of the hadoop related precommit jobs.
> The issue is that we have some tests in Common (and maybe HDFS) that purposefully set permissions within the {{target/}} directory to simulate a failure to interact with underlying fs data. The test sets some subdirectories to have permissions such that we can no longer delete their contents.
> Right now our precommit jobs include a step post-yetus-test-patch that traverses the target directories and ensures that all subdirectories are modifiable:
> {code}
> find ${WORKSPACE} -name target | xargs chmod -R u+w
> {code}
> Unfortunately, if we don't get to that line (say due to an aborted build, or if the call to yetus test-patch exceeds the job timeout), then we are left in a state where there are still subdirectories that can't be modified (including deleted).
> Our builds also currently attempt to run a {{git clean}} at the very start of the build after the repo is updated. If we have one of the aforementioned timeouts that leaves a can't-be-deleted test directory, then all future builds on that machine will fail attempting to run the {{git clean}} command.
