Hi @Ryanp ,   Here are the snippet from the knowledge article:   A workaround can be achieved using the steps below. (NMS=Navigator Metadata Server)   1. Identify IP address of the NMS. (can be gathered in Cloudera Management services->instances->Navigator Metadata Server)   2. Add the following line to the bottom of /etc/hosts on the NMS 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 <NMS_IP_ADDRESS> java.sun.com   3. On NMS, install httpd, depending on your Linux distribution. As this host does not have internet access, you will need to manually import and install rpms. https://httpd.apache.org/docs/2.4/platform/rpm.html   4. Make a directory for java dtd file, and adjust permissions. mkdir /var/www/html/dtd; chown 755 /var/www/html/dtd   5. Acquire Java DTD file from the following URL.   http://java.sun.com/dtd/web-app_2_3.dtd 6. Copy the file to /var/www/html/dtd directory on the NMS.  Ensure the file is readable by "other".   7. Enable httpd server sudo systemctl enable httpd; sudo systemctl start httpd   8. Start NMS.   NOTE: httpd must run for each NMS restart, this is not a one-off workaround. Systemctl command should ensure that this is the case.   If the above workaround is not possible, a patch is also available from Cloudera Support until this is resolved in an upcoming release of Cloudera Manager.   Thanks and hope this helps, Li ...

Hi @michalr ,   Here is the documentation you can follow on how to install NiFi: https://docs.hortonworks.com/HDPDocuments/CFM/CFM-1.0.0/installation/content/overview.html   Thanks, Li ... View more

Hi @gunjan ,   There is a new feature added in Hue latest version which it moves the source file to create table to a .scratchdir to handle moving file easily. However, if the create table fails, then there are files in .scratchdir left behind and future create tables fails. We have opened an internal jira to handle this in a better way.   Could you please remove the .scratchdir and try again as a workaround?   Thanks, Li ... View more

Hi @gunjan ,   Could you please share the versions of Hue you are using? Are you using upstream version or the vesion comes with CDH?   Thanks, Li ... View more

Hi @MantuDeka ,   Yes, if event server is not working, you won't be able to receive alerts. The alerts basically are the events which are marked as alerts based on CM configuration checking.   About Report Manager, we need to check the RM process logs and role log for more details about what went wrong. By default:   1) On the Report Manager host, find out the process logs: /var/run/cloudera-scm-agent/process/<process-ID>-cloudera-mgmt-REPORTSMANAGER/logs/stderr and stdout.log   2) On the same host, find out the role log: /var/log/cloudera-scm-headlamp/mgmt-cmf-mgmt-REPORTSMANAGER-<hostname>.log.out   Thanks and hope it helps, Li ...

Hi @MantuDeka ,   To second @gzigldrum 's feedback, you can find out more information from some logs. By default:   1) On the Event Server host, find out the process logs: /var/run/cloudera-scm-agent/process/<process-ID>-cloudera-mgmt-EVENTSERVER/logs/stderr and stdout.log   2) On the same host, find out the role log: /var/log/cloudera-scm-eventserver/mgmt-cmf-mgmt-EVENTSERVER-<hostname>.log.out   Thanks and hope it helps, Li ...
