srowen opened a new pull request #24407: [MINOR][TEST] Expand spark-submit test to allow python2/3 executable
URL: https://github.com/apache/spark/pull/24407
 
 
   ## What changes were proposed in this pull request?
   
   This backports a tiny part of another change:
   https://github.com/apache/spark/commit/4bdfda92a1c570d7a1142ee30eb41e37661bc240#diff-3c792ce7265b69b448a984caf629c96bR161
   ... which just works around the possibility that the local python interpreter is 'python3' or 'python2' when running the spark-submit tests.
   
   I'd like to backport to 2.3 too.
   
   This otherwise prevents this test from passing on my mac, though I have a custom install with brew. But may affect others.
   
   ## How was this patch tested?
   
   Existing tests.
