Keith Turner commented on ACCUMULO-84:
--------------------------------------
I think when the logger switches to read only, the tablet server should get an
error when trying to write to it. At that point the tablet server should
switch to another logger. If it can not find any logger, it will keep trying to
find a logger and writes will be held.
I think a requirement that the logger leaves READ-ONLY mode and enters
READ-WRITE mode once disk space becomes available is reasonable and desirable.
> Logger should fail into read-only mode with disk full

> If the disk is full for a Logger it will kill itself quickly. Instead we
> should have it fail into a 'read-only' mode, that way tservers can still do
> log recovery based on the data it has. It needs to be treated in such a way
> that tservers won't rely on it to log their new data, but can be used to
> recover older data.
