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

This ticket shows the exception as well. It could have the same cause for what we saw. Very least, this exception would help.

>                 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.
