Right, the TestCLI in Common has no tests, so one would expect that nothing would run. It's the TestHDFSCLI in HDFS that actually runs tests - it just inherits cross-project to this one.
Now that I look closer, the original hudson link was to the common TestCLI, which again has nothing in it.
The reason we started looking at this was the regression from
HADOOP-6375 which broke TestHDFSCLI but Hudson didn't pick it up. This is because that was a common patch and not an HDFS patch, and thus the tests against du weren't supposed to run.
Really the central issue here is that a common feature (FsShell) is being tested from HDFS. We should resolve this one as wontfix and open another JIRA to put the tests that cover FsShell in common and make TestHDFSCLI only test HDFS-specific stuff.
