Dmitry Ryabkov commented on ZOOKEEPER-2376:
-------------------------------------------
One of the possible fixes would be to model FileTxnLog after FileSnap which
skips over the "broken" files in its deserialize() method.
> Server fails to start if there is a zero-length TxnLog file present in the
> log directory
