             Summary: Re-enable blocksize-related tests under EC

                 URL: https://issues.apache.org/jira/browse/IMPALA-7098
             Project: IMPALA
          Issue Type: Sub-task
          Components: Frontend, Infrastructure
    Affects Versions: Impala 3.1.0
            Reporter: Tianyi Wang

In EC the unit of a scan range is a block group. So in our mini cluster a scan range is of 3X the size of a regular block. This breaks some tests under EC. One way to address this problem is to shrink the blocks to 1/3 of the original size in those tests.
