   +CC @Ngone51 Looks like there is an additional interaction between shuffle corruption diagnosis and push based shuffle.
   The underlying issue is a fetch failure - which also needs to be investigated (but gets suppressed due to the assertion failure).
   
   Failure to fetch push based shuffle chunks should have resulted in fallback to fetching the original shuffle blocks - needs to be investigated why it dropped down to diagnosis directly (CC @otterc )
