keith-turner opened a new issue, #5712:
URL: https://github.com/apache/accumulo/issues/5712

   **Describe the bug**
   
   When running the test described in #5707 w/o the fix in #5707 after the test 
got stuck observed that the zookeeper server was consistently using 100% CPU 
for long periods of time.  Not sure if it was doing this before the test got 
stuck.  This needs to further investigation to see if Accumulo is accessing 
zookeeper too aggressively under certain situations.  
   
   **To Reproduce**
   
   Could try running the bulk random walk test using external compaction w/o 
the fix in #5707 and monitor zookeeper CPU usage.  The high CPU utilization was 
observed after the user compaction was stuck, not sure what the CPU utilization 
looked like before that.  Would be good to look at the utilization in general 
when running some random walk and continuous ingest test.
   
   **Expected behavior**
   
   A single node cluster w/ light activity from a random walk test should 
probably not be pushing zookeeper to 100% cpu utilization.  If the activity is 
reasonable, then it would be good to understand it.  Suspect something in the 
manager is reading zookeeper too aggressively.
