Description

As part of Namenode startup progress, we have multiple phases and steps within phase that are instantiated. While the startup progress view can be instantiated with the current view of phase/step, having at least DEBUG logs for startup progress would be helpful to identify when a particular step for LOADING_FSIMAGE/SAVING_CHECKPOINT/LOADING_EDITS was started and ended.
