@GangWar Thanks for your suggestion. All the parameters except the following one were already set in /etc/cloudera-scm-agent/config.ini verify_cert_file Apparently, the only reason why agent wasn't serving requests for logs was because the above flat wasn't set. The moment we configured the flag verify_cert_file and restarted agent, it started serving logs correctly.

Hi Guys, the solution was to change the browser that I use. The erroneous browser is my Chrome Version 80.0.3987.132 (Official Build) (64-bit) with some AD blockers installed. Everything seems to be fine when I changed to Microsoft Edge so I will try other browsers among a clean install of Chrome as well. Sorry for the inconvenience and thanks for your efforts.

Hi @GangWar , Thanks for your sharing, how ever I tried with image apache/nifi:latest https://hub.docker.com/r/apache/nifi/ My expectation is mount folder /opt/nifi/nifi-current/conf (inside nifi-container) to folder nifi (in docker-machine). However it doesnot work. Do you have any suggestions?

@nkim When you said randomly does this mean it's working sometimes without any manual intervention. The klist command showing there there is no credentials found, have you checked if some process or software is deleting this "kdestroy" periodically? Else KRB trace can a good start here.

@Rah It's worth to check if you have TLS enabled installation. I see a note in doc which needs out attention. If you have enabled Auto-TLS, you must include the Cloudera Manager server host when you specify hosts. https://docs.cloudera.com/cdpdc/7.0/installation/topics/cdpdc-install-runtime-using-wizard.html Did you restart CM after disabling TLS? Also, when you are using the add host wizard, you do not want to set use_tls=1 until the host is successfully added. It is actually kind of a messy procedure: 1. Disable Use TLS Encryption for Agents, and Use TLS Authentication of Agents to Server. 2. Restart CM 3. Add host to CM 4. Turn on Use TLS Encryption for Agents, and Use TLS Authentication of Agents to Server. 5. Configure agent to use TLS (setting use_tls=1 and the cert/key parameters, or copy config.ini from another host with TLS enabled). 6. Restart agent Alternatives: Use Auto-TLS introduced in C6 Follow the "Alternate Method of installing Cloudera Manager Agent without Disabling TLS" steps instead. If above does not help then we need full log file from CM server to take a look. Cheers,

@P_Suresh_Rao The reason on your ask is as per my guess is that QuickStart VM don't have internet access. If yes then you can download packages externally and then copy into QuickStart and install something like: $ sudo yum update
$ sudo yum install yum-utils You can then install the CentOS IUS package which will get you up to date with their site: $ sudo yum install https://centos7.iuscommunity.org/ius-release.rpm Finally you can then install Python and Pip: $ sudo yum install python36u
$ sudo yum install python36u-pip If the QuickStart have internet access then you can just update Python like any other packages with yum update command. https://developers.redhat.com/blog/2018/08/13/install-python3-rhel/

Finally, I figured out what is going on. The root cause is that, I only set up testuser on edge nodes, not the name node. I looked into this page, https://hadoop.apache.org/docs/r3.1.1/hadoop-project-dist/hadoop-common/GroupsMapping.html, which shows that "For HDFS, the mapping of users to groups is performed on the NameNode. Thus, the host system configuration of the NameNode determines the group mappings for the users." After I created the user on the NameNode and ran the command hdfs dfsadmin -refreshUserToGroupsMappings the copy is successful and there is no permission-denied error.

@CaptainJa The version of Tomcat used in CDH 5.16.2 should not have any vulnerabilities. Could you share the CVE that is reported CDH is vulnerable to? Per the notice [1] independent upgrade of Tomcat is not supported and we are moving towards newer versions in CDH6 => Cloudera Enterprise 6 has replaced Tomcat 6 with Jetty 9 and is not susceptible to Tomcat security issues.
