> 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:
> {noformat}
> ...
> self.cluster.catalogd.start()
> ...{noformat}
> Results in catalogd exiting with the following, indicating the env for Java is not as expected:
> {noformat}
> 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
> {noformat}
> Making this easier will make it easier to test more scenarios that restart processes.
> Note that starting statestored works fine (no Java).
