voldemort.cluster.failuredetector.BannagePeriodFailureDetector
BannagePeriodFailureDetector relies on external callers to notify it of failed attempts to access a node's store via recordException. When recordException is invoked, the node is marked offline for a period of time as defined by the client or server configuration. Once that period has passed, the node is considered available. However, BannagePeriodFailureDetector's definition of available uses a fairly loose sense of the word. Rather than considering the node to be available for access, it is available for attempting to access. In actuality the node may still be down. However, the intent is simply to mark it down for N seconds and then attempt to try again and repeat. If the node is truly available for access, the caller will then invoke recordSuccess and the node will be marked available in the truest sense of the word. @see VoldemortConfig#getFailureDetectorBannagePeriod @see ClientConfig#getFailureDetectorBannagePeriod @see FailureDetectorConfig#getBannagePeriod
