can we use a new JIRA ticket? The original ticket is for 4.1 but this change is apparently master branch only. |

What changes were proposed in this pull request?
Enable checksum based indeterminate shuffle retry by default.
Increase jvm memory size to 6g for
sqlmodule tests, as test case SPARK-48037: Fix SortShuffleWriter lacks shuffle write related metrics resulting in potentially inaccurate data set shuffle partition as16777216which will need more memory for computing order independent shuffle checksum.Why are the changes needed?
As checksum based solution is more accurate to detect indeterminate shuffle output changes, propose to enable it by default to avoid query correctness issues caused by indeterminate shuffle retry.
