> 2012-04-03 18:54:47,172 WARN org.apache.hadoop.hbase.io.hfile.HFile: Dropping
> fs latency stats since buffer is full
> {noformat}
> While the code says this:
> {noformat}
> // we don't want to fill up the logs with this message, so only log it
> // once every 30 seconds at most
> // I also want to avoid locks on the 'critical path' (the common case will
> be
> // uncontended) - hence the CAS
> private static void logDroppedLatencyStat() {
> {noformat}
> It doesn't seem like this message is actionnable and even though it's printed
> "only" every 30 seconds it's still very spammy.
> We should get rid of it or make it more useful (I don't know which).
