Kaiyao Ke updated MAPREDUCE-7475:
---------------------------------
Flags: Patch
Description:
2 tests are not idempotent and fails upon repeated execution within the same
JVM instance due to self-induced state pollution. Specifically, these tests try
to make the directory TEST_ROOT_DIR and write to it. The tests do not clean up
(remove) the directory after execution. Therefore, in the second execution,
TEST_ROOT_DIR would already exist and the exception `Could not create test dir`
would be thrown. Below are the 2 non-idempotent tests:
* org.apache.hadoop.mapred.TestOldCombinerGrouping.testCombiner
* org.apache.hadoop.mapreduce.TestNewCombinerGrouping.testCombiner
Environment: Ubuntu 22.04, Java 17
Summary: 2 tests are non-idempotent (passes in the first run but
fails in repeated runs in the same JVM) (was: 2 tests are non-idempotent
(passes in the first run but fails in repeated runs in the same JVM):)
Remaining Estimate: 10m
Original Estimate: 10m
> 2 tests are non-idempotent (passes in the first run but fails in repeated
