Digging around, I ran into the failures_before_use_standby setting. It looks like is_standby_exception isn't detecting the exception correctly.

Here is a check:

e.is_a?(WebHDFS::IOError) && e.message.match(/org\.apache\.hadoop\.ipc\.StandbyException/)

So the problem is StandbyException happens with non WebHDFS::IOError?
