> Some precommit jobs have been hitting intermittent test failures on DataCacheTest.SetReadOnly:
> {noformat}
> /home/ubuntu/Impala/be/src/runtime/io/data-cache-test.cc:165
> Expected: (cache_misses) > (0), actual: 0 vs 0{noformat}
> The test has a race condition that means it can't guarantee that the cache_misses is strictly greater than zero.
