I didn't see firm reproduction of the issue if drastically reducing the number 
of sessions and rows written, and the scenario under TSAN is still flaky even 
if reducing the load to barely have the issue reproducing itself: 
http://dist-test.cloudera.org//job?job_id=aserbin.1621804245.42503#

What aspect you don't like particularly in skipping tests for ASAN/TSAN 
binaries?  We have multiple tests like that for the backend, where the whole 
test scenario is skipped:
  * TestCFileBothCacheMemoryTypes.TestReadWriteLargeStrings (skipped)
  * ThreadPoolTest.TestDeadlocks (skipped)
  * DebugUtilTest.TestUnwindWhileUnsafe (skipped)
  * TsRecoveryITestDeathTest.TestRecoverFromOpIdOverflow (skipped)

Also, about hundred of test scenarios has special settings for ASAN/TSAN builds.

In this context we are not testing the back-end as is, so what's wrong with 
skipping the test if running against binaries built with ASAN/TSAN?
