I recently ran into this problem when trying to repro IMPALA-6907. The fix is
to use {{bin/bin/start-impalad.sh}} to restart the Impala instance instead of
exec'ing Impald directly. I can post the fix along with the patch for

> Cluster test API unable to (re)start processes
> ----------------------------------------------
>
> Key: IMPALA-6962
> URL: https://issues.apache.org/jira/browse/IMPALA-6962
> Project: IMPALA
> Issue Type: Bug
> Components: Infrastructure
> Affects Versions: Product Backlog
> Reporter: Vuk Ercegovac
> Priority: Major
>
> 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).
