Keith Turner commented on ACCUMULO-2217:
----------------------------------------

I think we should do both.   Logging a warning and falling back to gz would be a good way to keep a misconfigured node from gumming things up.  Checking a random tserver when setting the config would also be nice.  Could create two sub task.

>             Project: Accumulo
>          Issue Type: Bug
>    Affects Versions: 1.4.4, 1.5.0
>            Reporter: Adam Fuchs
>
> Bad compression configuration keeps tables online:
> {code}
> createtable test
> config -t test -s table.file.compression.type=snappy
> flush
> droptable test
> {code}
> The flush results in an unsatisfied link error when Snappy is not properly configured. This keeps the tablet online. Dropping the table when the tablet is stuck online puts a FATE operation in the queue, which backs everything up.
> Can we fall back to something that is in the java code base (i.e. gz) in the event of failures to load other compression code?
