Allen Wittenauer commented on HDFS-12711:
-----------------------------------------

bq. We usually try to rerun the failed tests locally to check if they are related to the patch. 

I think this may be the key as to why I don't think enough people are in panic mode. Let's take Erik's log as an example.  It's from HDFS-12823.  Precommit reported ~20 tests that either failed or timed out.  It reaped 20 excess surefire jvms after mvn returned.  The asflicense check came back with 130 dump log files.  Those 130 dump log files in almost every case I looked at were not reported to surefire.  That means that we're probably looking at a minimum of 150 tests failed, not 20. Given that those 120 broken JVMs likely had more than 1 test...

We're basically dropping a very large percentage (maybe even the majority) of test results on the ground.
