azagrebin opened a new pull request #10608: [FLINK-15300][Runtime] Fix sanity 
check to not fail if shuffle memory fraction is out of min/max range
URL: https://github.com/apache/flink/pull/10608
 
 
   ## What is the purpose of the change
   
   If we have a configuration which sets shuffle memory min/max value then the 
sanity check (TaskExecutorResourceUtils#sanityCheckShuffleMemory) can fail if 
the fraction is out of min/max range because it checks that the fraction 
exactly matches the derived min/max value.
