@pdev  As per Hadoop Doc:    https://hadoop.apache.org/docs/r2.7.0/hadoop-project-dist/hadoop-hdfs/hdfs-default.xml The default configuration for "dfs.webhdfs.enabled" is "true". Which means if you do not see it in hdfs-site.xml means it is by default enabled.  You can override it by editing the "hdfs-site.xml" based on your requirement. dfs.webhdfs.enabled true Enable WebHDFS (REST API) in Namenodes and Datanodes. ...

@irfangk1 Looks like the SmartSense service installation is failing for you.   Failed to execute command: dpkg-query -l | grep 'ii\s*smartsense-*' || apt-get -o Dpkg::Options::=--force-confdef --allow-unauthenticated --assume-yes install smartsense-hst || dpkg -i /var/lib/ambari-agent/cache/stacks/HDP/3.0/services/SMARTSENSE/package/files/deb/*.deb; Exit code: 1; stdout: ; stderr: E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem. dpkg: error processing archive /var/lib/ambari-agent/cache/stacks/HDP/3.0/services/SMARTSENSE/package/files/deb/*.deb (--install): cannot access archive: No such file or directory   Thats the reason later at Step9 the services are failing to start because smartsense service binaries (due to package installation failure) are not present.   INFO 2019-09-24 16:06:03,584 ComponentStatusExecutor.py:172 - Status command for HST_AGENT failed: Failed to execute command: /usr/sbin/hst agent-status; Exit code: 127; stdout: ; stderr: /bin/sh: 1: /usr/sbin/hst: not found   Better to skip and proceed the Step9 by clicking Next/Proceed/OK/Complete kind of button in UI and then later verify on the Host where the SmartSense package is supposed to be install and failing to install.   Check if the repo is fine and if you are manually able to install the SmartSesne binary on that host? It might be some ambari repo access issue on that node where the SmartSense installation failed. Better to check and share the exact OS version and the ambari repo version.   Like based on the ambari version please get the correct repo something like: # wget -O /etc/apt/sources.list.d/ambari.list <a href="http://public-repo-1.hortonworks.com/ambari/XXXXXXXXXXXXXX/updates/2.7.3.0/ambari.list" target="_blank">http://public-repo-1.hortonworks.com/ambari/XXXXXXXXXXXXXX/updates/2.7.3.0/ambari.list</a> # apt-get clean all # apt-get update You can get the correct ambari REPO URL from the following kind of links: https://docs.cloudera.com/HDPDocuments/Ambari-2.7.3.0/bk_ambari-upgrade-major/content/upgrade_ambari.html . . ...
