Thanks for your answer and also for the warning about the version in the stack. Current Spark2 version is 2.2.0. I am going to correct it on question. And also both answers are good news to me. Thanks again.

Hello @Aditya Sirna Thank you for your answer. I have added the parameter with a value of 0 but got an exception (HDP 2.6.3.0 on CentOS 7.2) 2018-03-20 21:09:48,207 ERROR namenode.FSNamesystem (FSNamesystem.java:<init>(913)) - FSNamesystem initialization failed. java.lang.IllegalArgumentException: Cannot set dfs.namenode.fs-limits.max-directory-items to a value less than 1 or greater than 6400000 Thus, I doubled the old value (4194304) and now it works. Will HDFS be removing the tmp dir? Is there any preset period of configuration for that? Otherwise may tmp dir exceed the new limit? Or may hdfs get OOM exception while cleaning it like i got trying to clean manually? You can check my other question if you have a comment on it. https://community.hortonworks.com/questions/179904/having-issue-with-tmp-directory-removal.html

@Geoffrey Shelton Okot Unfortunately, I couldn't start HDFS services this way, neither. Thank you very much though.

You are awesome enough to thank so much! 🙂 I was expecting just to see if the behaviour I see is normal but your explanation to me like teaching to fish instead of giving it. I have learned the procedure instead, how it worked. Thanks again! 😄

Answer appeared on second comment. Thanks @Arpit Agarwal ! By the way, port number is 1022 On /etc/hadoop/conf/hdfs-site.xml file <property> <name>dfs.datanode.http.address</name> <value>0.0.0.0:1022</value> </property> Yes, my environment is Kerberos enabled. It was already represented on Namenode UI > Datanodes tab > "Http Address" column.
