NameNode usually enters the safemode and I can't write anything or copy data to HDFS until i execute -dfsadmin samemofe leave?
I have no idea what causes this frequent action that NameNode enters the safemode because of, and I would like to know if there anyway to overcome this action or at least stop it from happening everything might be some data are missing or whatever causing this ?
