@Kant T File View will allow to upload binary files, However you can only view/read the Text files via Ambari View. Binary files (Like PDF/ Image files) are not supposed to be displayed fine in File View.

@Michael Bronson As the AMS collector seems to be running it should collect and show the data however we will need to check if AMS collector has the data or not? So in order to check that we will need to capture the following informations: 1. Need to make an API call to the AMS collector in order to list down the number & names of metrics that it is collecting? and from which hosts. The following URLs will give us JSON output . Can you please share the same here. http://<ams-host>:6188/ws/v1/timeline/metrics/metadata http://<ams-host>:6188/ws/v1/timeline/metrics/hosts 2. Need to check the Binaries of ambari collector and sink (so that we can see if it is same as ambari ersion) # rpm -qa | grep ambari 3. Can you please check if the metrics-monitor logs shows any kind of connectivity error while connecting to AMS collector? # /var/log/ambari-metrics-monitor/ambari-metrics-monitor.out 4. Do we see if the hostname resolution if file and correctly defined inside the "/etc/ambari-metrics-monitor/conf/metric_monitor.ini" file 5. Please check if the AMS collector log shows any error? ...

@panitta suksaran As we see the error, Where it looks like you have not setup MySQL server for Hive properly. Please see: https://docs.hortonworks.com/HDPDocuments/Ambari-2.6.1.0/bk_ambari-administration/content/using_hive_with_mysql.html raise Fail("Failed to download file from {0} due to HTTP error: {1}".format(self.url, str(ex))) resource_management.core.exceptions.Fail: Failed to download file from http://xxxxxx:8080/resources//mysql-connector-java.jar due to HTTP error: HTTP Error 404 So please make sure that you have already done the following steps? On the Ambari Server Host. # yum install mysql-connection-java -y (OR) if you are downloading the mysql-connector-java JAR from some tar.gz archive then please make sure to check the following locations and create the symlinks something like following to point to your jar. . Then you should find some symlink as following: Example: # ls -l /usr/share/java/mysql-connector-java.jar lrwxrwxrwx 1 root root 31 Apr 19 2017 /usr/share/java/mysql-connector-java.jar -> mysql-connector-java-5.1.17.jar https://docs.hortonworks.com/HDPDocuments/Ambari-2.6.1.0/bk_ambari-administration/content/using_hive_with_mysql.html So now ambari knows how to find this jar. The JAR can be found here after # ambari-server setup --jdbc-db=mysql --jdbc-driver=/usr/share/java/mysql-connector-java.jar # ls -l /var/lib/ambari-server/resources/mysql-connector-java.jar -rw-r--r-- 1 root root 819803 Sep 28 19:52 /var/lib/ambari-server/resources/mysql-connector-java.jar Reference HCC Thread: https://community.hortonworks.com/questions/186090/mysql-connector-javajar-due-to-http-error-http-err.html . ...
