             Summary: Consider removing --disable_mem_pools debugging feature
                 Key: IMPALA-6507
                 URL: https://issues.apache.org/jira/browse/IMPALA-6507
             Project: IMPALA
          Issue Type: Improvement
          Components: Backend
    Affects Versions: Impala 2.11.0
            Reporter: Tim Armstrong
            Assignee: Tim Armstrong

We should consider removing support for the --disable_mem_pools feature. It was 
originally somewhat useful for debugging memory-related issues where memory 
pooling could limit the effectiveness of ASAN's checks. However, now we use 
ASAN's poisoning in all cases, which provides most of the same coverage and is 
used by default with ASAN.

We don't routinely test --disable_mem_pools so we should consider removing it 
to save the burden of maintaining these extra code paths.
