Description

An exhaustive run on centos 6 hit the following error:

custom_cluster/test_breakpad.py:319: in test_minidump_cleanup_thread
    assert self.wait_for_num_processes('impalad', cluster_size) == cluster_size
custom_cluster/test_breakpad.py:120: in wait_for_num_processes
    num_processes = self.get_num_processes(daemon)
custom_cluster/test_breakpad.py:105: in get_num_processes
    self.cluster.refresh()
common/impala_cluster.py:87: in refresh
    self.__build_impala_process_lists()
common/impala_cluster.py:209: in __build_impala_process_lists
    cmdline = process.cmdline
../infra/python/env/lib/python2.6/site-packages/psutil/__init__.py:330: in cmdline
    return self._platform_impl.get_process_cmdline()
../infra/python/env/lib/python2.6/site-packages/psutil/_pslinux.py:437: in wrapper
    raise NoSuchProcess(self.pid, self._process_name)
E   NoSuchProcess: process no longer exists (pid=6572, name='impalad')

In looking at the logs, I don't see an impalad with that pid, so it would have to be a breakpad process.
