Subject [jira] [Commented] (ACCUMULO-1771) Instance id and version info only stored on one hdfs instance

Christopher Tubbs commented on ACCUMULO-1771:
---------------------------------------------

{quote}What's the use case for running Accumulo with different kinds of volumes?{quote}

Well, there's possibly {{tmpfs}}, with a custom {{general.volume.chooser}}. But, also, generally,
there's the use case of expansion or combining two instances.

In general, I'd probably not recommend using two different kinds of filesystems, but I do
think Accumulo should be agnostic to the implementation of the volume.

> When instance.volumes contains multiple uris only the first one is initialized with the
data version and instance id.   If the user changes the order of the uris in the config, it
seems like Accumulo will stop working correctly.
