Description

The API's to control cluster processes (tests/common/impala_cluster.py) do not start processes correctly. When Process::start() is called from pytests, the process dies immediately. For example:

...
self.cluster.catalogd.start()
...

Results in catalogd exiting with the following, indicating the env for Java is not as expected:

I0502 14:50:05.983942 26535 status.cc:125] Failed to find JniUtil class. 
    @    0x17600bd impala::Status::Status() 
    @ 0x1bda29a impala::JniUtil::Init() 
    @ 0x1759478 impala::InitCommonRuntime() 
    @ 0x1702da5 CatalogdMain() 
    @ 0x17028ef main 
    @ 0x7f503f139830 __libc_start_main 
    @ 0x1702739 _start

Making this easier will make it easier to test more scenarios that restart processes.

Note that starting statestored works fine (no Java).
