Subject [jira] [Commented] (ACCUMULO-4086) Allow configurable failsafe volume choosing
Date Wed, 06 Jan 2016 19:12:39 GMT


Matt Peterson commented on ACCUMULO-4086:

Another option, which Christopher and I discussed, is for the PreferredVolumeChooser to not
fallback at all but to instead throw an exception if it encounters a misconfiguration or other
error.  Then the caller can handle this appropriately, whether that caller is the PerTableVolumeChooser
or VolumeManagerImpl.

> 3. In several places including {{PreferredVolumeChooser}}, {{PerTableVolumeChooser}}
and {{VolumeManagerImpl}}, the failsafe chooser is the {{RandomVolumeChooser}} which will
include the instance volume that needs to be excluded.  It would be useful to have a configurable
failsafe in this situation.
