What changes were proposed in this pull request?
Modify StatsUtils.estimateStatsForMissingCols to return a new list of column statistics instead of adding the newly estimated stats to its input parameter.
Why are the changes needed?
When reading the column statistics of an Iceberg table fails, Collections.emptyList() is returned. Because this is an unmodifiable list, the current implementation of estimateStatsForMissingCols tries to add the estimated column statistics to it and an exception is thrown.
Does this PR introduce any user-facing change?
No.
