   Reverting a PR is very common if we have some mistakes in the PR, we can 
apply it later after fixing the mistakes.
   
   At least we should not increase the test timeout limit, and also the load 
balancer change.
   
   And on the tmp directory fix, could you please paste the log sections which 
shows problems for sharing tmp directory? Or you can paste the AI chat log and 
the full log file it mentioned so we can review it.
   
   > Just to add a little more context, I started with a couple of fixes, but 
when the fix PR itself started hitting new flapper, I kept diagnosing and 
adding fixes to the same PR until I got a green build.
   
   I'd say this is common in HBase, that's why we have a flaky dashboard to 
show flaky tests. Starting a mini cluster in test is heavy and easy to have 
races when running on a slow machine...
   
   On the AI tool, Sonnet 4.5 is not powerful enough, Opus 4.6 will be bettter. 
And for debugging flaky tests, I recommend use Codex 5.4 xhigh since HBase is a 
project live for more than 15 years, we have lots of strange code in our code 
base, you need to think more and more before actually doing things...
