Flavio Junqueira commented on ZOOKEEPER-1453:
---------------------------------------------

I'm glad it worked, Marshall.

bq. there is still a potential issue with corruption from a reboot that should 
be addressed under this jira.

In my understanding, the partial writes during syncs that Bill is referring to 
would be captured by the crc checks. Is this not enough?

> See ZOOKEEPER-1449 for background on this issue. The main problem is that 
> during server recovery 
> org.apache.zookeeper.server.persistence.FileTxnLog.FileTxnIterator.next() 
> does not indicate if the available logs are valid or not. In some cases (say 
> a truncated record and a single txnlog in the datadir) we will not detect 
> that the file is corrupt, vs reaching the end of the file.
