I see now why I misunderstood. I took "see a X which tells that Y" to mean "you will see X and you should interpret it to mean Y" rather than the intended "you will see X and it will contain details that Y". suggested edit for this sentence: > If you have not enabled the rsgroup feature and you call any of the rsgroup admin methods or shell commands the call will fail with a `DoNotRetryIOException` with a detail message that says the rsgroup feature is disabled. wdyt? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
