Subject [jira] [Created] (ACCUMULO-3600) ShellServerIT.deleteRows might fail
Date Tue, 17 Feb 2015 23:23:11 GMT
Josh Elser created ACCUMULO-3600:

             Summary: ShellServerIT.deleteRows might fail
                 Key: ACCUMULO-3600
             Project: Accumulo
          Issue Type: Bug
          Components: test
    Affects Versions: 1.6.1
            Reporter: Josh Elser
            Assignee: Josh Elser
            Priority: Minor
             Fix For: 1.7.0, 1.6.3

Saw a failure in {{ShellServerIT#deleteRows}} where one tablet had 2 files instead of the
expected one. The test roughly does the following:

1. Create a table
2. Add 2 splits to that table (3 tablets)
3. Add 10 records (split "evenly" across the tablets)
4. Flush the table (spill memory to disk)
5. Check that each tablet has one file.

The problem with the test is that while step 3 is happening, one of the new tablets could
be migrated to the other tablet server. This would cause a minc (and write a file). Step3
would eventually finish, and then step4 would cause another minc (and file) on the tablet
that was migrated. This would result in two rfiles for the tablet instead of the expected

Need to update the test so that it accounts for this possibility.
