   ## What it costs to run hudi-cli again
   
   The module was dropped from the catch-all lists to cut CI runtime, so here 
is the measured price of putting it back, from #18816's Azure logs vs the 12 
most recent successful builds on other PRs:
   
   - **Azure**: `UT_FT_10` (`UT FT common & other modules`) goes from ~73 to 
~83 min. The reactor summary pins it on `hudi-cli` itself: 9:19 / 9:38 / 10:27 
in the functional-test invocation and 16-18 s in the unit-test one. That phase 
alone goes 3:50 -> ~13:45, since the functional suite starts a SparkSession per 
test class. No other Azure job changes.
   - **GitHub Actions**: #18816 adds `test-hudi-cli` as its own job, 19.0 min 
(8.6 install, 0.3 UT, 9.7 FT) against a 72.3 min critical path. No wall-clock 
change, +19 runner-minutes out of 607.
   
   So ~10 min on one Azure job for 113 tests and the module's coverage going 
~15% -> ~43%.
   
   Caveat for anyone re-measuring: `UT_FT_10`'s install phase swings 15:39 to 
40:09 across builds, so comparing job totals between PRs measures agent luck, 
not tests. Per-invocation table in
