HDFS Corrupt after new install.
Summary: I installed 2.1, then I went to do other things which I have to attend to. The cluster sat idle with nothing happening (It’s not yet being used, this was a prep load) for about 12 days. I have now come back and HDFS is complaining in Ambari so I ran a few checks. Below is the information I have. I don’t understand how these things got corrupted with nothing happening in the cluster except sitting idle. It is concerning that it got corrupted on a new install with nothing happening. Ideas?
