There was a problem hiding this comment.
This language is specific to internal naming. It might be better to say something like this:
The maximum number of completed applications to display. Older applications will be dropped from the UI to maintain this limit.
And likewise below.

…id unnecessary sort operations
### What changes were proposed in this pull request?
This pull request tries to normalize the SortOrder properly to prevent unnecessary sort operators. Currently the sameOrderExpressions are not normalized as part of AliasAwareOutputOrdering.
Example: consider this join of three tables:
"""
|SELECT t2id, t3.id as t3id
|FROM (
| SELECT t1.id as t1id, t2.id as t2id
| FROM t1, t2
| WHERE t1.id = t2.id
|) t12, t3
|WHERE t1id = t3.id
""".
The plan for this looks like:
*(8) Project [t2id#1059L, id#1004L AS t3id#1060L]
+- *(8) SortMergeJoin [t2id#1059L], [id#1004L], Inner
:- *(5) Sort [t2id#1059L ASC NULLS FIRST ], false, 0 <-----------------------------
: +- *(5) Project [id#1000L AS t2id#1059L]
: +- *(5) SortMergeJoin [id#996L], [id#1000L], Inner
: :- *(2) Sort [id#996L ASC NULLS FIRST ], false, 0
: : +- Exchange hashpartitioning(id#996L, 5), true, [id=#1426]
: : +- *(1) Range (0, 10, step=1, splits=2)
: +- *(4) Sort [id#1000L ASC NULLS FIRST ], false, 0
: +- Exchange hashpartitioning(id#1000L, 5), true, [id=#1432]
: +- *(3) Range (0, 20, step=1, splits=2)
+- *(7) Sort [id#1004L ASC NULLS FIRST ], false, 0
+- Exchange hashpartitioning(id#1004L, 5), true, [id=#1443]
+- *(6) Range (0, 30, step=1, splits=2)
In this plan, the marked sort node could have been avoided as the data is already sorted on "t2.id" by the lower SortMergeJoin.
### Why are the changes needed?
To remove unneeded Sort operators.
### Does this PR introduce any user-facing change?
No
### How was this patch tested?
New UT added.
Closes #30302 from prakharjain09/SPARK-33400-sortorder.
