[GitHub] keith-turner opened a new issue #20: Make continuous ingest delete data

keith-turner opened a new issue #20: Make continuous ingest delete data
URL: https://github.com/apache/accumulo-testing/issues/20
 
 
   apache/accumulo#537 was a WAL recovery bug where deleted data could possibly come back.  This flaw was not found through testing.  It would be nice to delete data in the continuous ingest test to cover this case.  This could be done by periodically deleting a previously written set of linked list.  The linked list would need to be deleted in reverse order to avoid false positives in the test. Could do something like the following.
   
   ```
   while (true) {
      //write linked 1,000,000 linked list of 25 nodes
      if(random.nextInt(10) == 0) {
          //delete previously written 1,000,000 linked list of 25 nodes in reverse order
      }
   ```
