alamb opened a new issue, #18476:
URL: https://github.com/apache/datafusion/issues/18476

   ### Describe the bug
   
   A test in shuffle.slt fails  intermittently but passes on rerun
   
   ### To Reproduce
   
   Here is an example:
   
   https://github.com/apache/datafusion/actions/runs/19022758025/job/54320962649
   
   ```
        Running bin/sqllogictests.rs 
(target/ci/deps/sqllogictests-3c0c5297e9072553)
   External error: 1 errors in file 
/__w/datafusion/datafusion/datafusion/sqllogictest/test_files/spark/array/shuffle.slt
   
   1. query result mismatch:
   [SQL] SELECT shuffle([1, 2, 3, 4, 5, NULL]) != [1, 2, 3, 4, 5, NULL];
   [Diff] (-expected|+actual)
   -   true
   +   false
   at 
/__w/datafusion/datafusion/datafusion/sqllogictest/test_files/spark/array/shuffle.slt:24
   ```
   
   ### Expected behavior
   
   Test should always pass
   
   ### Additional context
   
   I suspect the issue is that in very rare occasions the two calls to shuffle 
result in the exact same output
