> do you recommend similar treatment for FileSystemConfigStorage also?
yep, HDFS although is not a posix filesystem, but renaming a file is still
implemented as an atomic operation.
might want to consider moving atomicWriteToFile() to ConfigStorage so both
LocalConfigStorage and FileSystemConfigStorage can use it.---
