Jean-Marc Spaggiari commented on HBASE-9996:
--------------------------------------------

sgtm

Any risks that this.fs.getFileStatus(oldFile).getLen() changes between the sync 
and when it's called just after?

> move the log io operation out of updateLock scope

> I am working at another write outlier issue, and just saw this code pattern:
> {code}
> synchronized(updateLock) {
> ...
> LOG.info(xxx)
> ...
> }
> {code}
> let's move the log statement out of this sync block.  seems it's ok in trunk 
> code, just a 0.94 issue
