SammiChen commented on HDFS-11643:
----------------------------------
Thanks [~andrew.wang] and [~jojochuang] for your review effort! Andrew, I got
your point. Yes. It's better if we can check a file is striped or not without
introducing an additional RPC call.

> At startup, the balancer writes its hostname to the lock file and calls
> hflush(). hflush is not supported for EC files, so this fails when the entire
> filesystem is erasure coded.
