DataNode Max Log Size -> ' the default value is 200 MB' - you can reduce as needed 4. DataNode Maximum Log File Backups -> ' the default value is 10' - you can reduce as needed 5. NameNode Max Log Size -> 'the default value is 200 MB' - you can reduce as needed 6. NameNode Maximum Log File Backups -> 'the default value is 300' - you can reduce as needed NOTE: I am repeating again, please consider the point a & b before you take action Tue, 17 Apr 2018 14:58:32 GMT saranvisa 2018-04-17T14:58:32Z
