testAddRegionWithCompactions

public void testAddRegionWithCompactions()
                                  throws Exception

Tests adding a region to the snapshot manifest while compactions are running on the region. The idea is to slow down the process of adding a store file to the manifest while triggering compactions on the region, allowing the store files to be marked for archival while snapshot operation is running. This test checks for the correct behavior in such a case that the compacted files should not be moved around if a snapshot operation is in progress. See HBASE-18398

Throws:

Exception

addRegionToSnapshot
