Hi Syed,
As per the HA image, Below are my questions...
1) the common share drive will maintain the edit logs and FSImage or only edit logs?
2) How the Standby Namenode does know that Active NameNode written some thing into edit logs at common drive ? I mean is the Standby NN will keep check the status in edit log at common drive or how technically it checks the updates?
3) The DataNode will send the heartbeats & Block report to NameNode - so what is the time frequency? which file we can...
