Description: Currently, blink planner will use default rowCount value
(defined in {{FlinkPreparingTableBase#DEFAULT_ROWCOUNT}} ) when the statistics
is unknown, and maybe choose one-phase Aggregate. The job will hang if the data
is skewed. So It's better to use two-phase Aggregate for execution stability if
the statistics is unknown. (was: Currently, blink planner will use default
rowCount value (defined in {{FlinkPreparingTableBase#DEFAULT_ROWCOUNT}} ) when
the statistics is unknown, and maybe choose {{HashJoin}} instead of
{{SortMergeJoin}}. The job will hang if the build side of {{HashJoin}} has huge
input size. So It's better to use {{SortMergeJoin}} for execution stability if
the statistics is unknown.)
