------------------------------------

             Summary: BulkImporter.getAssignments provides unhelpful exception with bad file
permissions
                 Key: ACCUMULO-3377
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-3377
             Project: Accumulo
          Issue Type: Bug
          Components: tserver
    Affects Versions: 1.6.0
            Reporter: John Vines


BulkImporter.getAssignments has the following code block
{code}          try {
            tabletsToAssignMapFileTo = findOverlappingTablets(ServerConfiguration.getSystemConfiguration(instance),
fs, locator, mapFile, credentials);
          } catch (Exception ex) {
            log.warn("Unable to find tablets that overlap file " + mapFile.toString());
          }
          log.debug("Map file " + mapFile + " found to overlap " + tabletsToAssignMapFileTo.size()
+ " tablets");
{code}

In that call to find findOverlappingTablets, it is possible for an exception to occur that
relates to an inability for the tserver to read the given file. Unfortunately, the exception
isn't used in the log message and we provide no real feedback that the file cannot be read.
We just fail it.

I don't expect for us to magically recover, but we do need to log the exception as well to
help make clear why this happened.
