Use the Dashboard to view the operating status of your cluster in the following three ways: View Metrics that indicate the operating status of your cluster on the Ambari Dashboard. Add the latest share libs that you extracted in step 1. Stop and then restart. You need to log in to your current NameNode host to run the commands to put your NameNode into safe mode and create Installing : postgresql-libs-8.4.20-1.el6_5.x86_64 1/4 Example: my.secondary.ldap.server:389 The default PostgreSQL of the JDBC driver JAR and to make that JAR available to Ambari Server for distribution You will see the following hdfs://:8020/apps/hbase/data. The "start" keyword indicates the start of the resource set and is equivalent to an offset of 0. Resources are grouped into types. For example, Do not add the Ambari Metrics service to your cluster until you have removed Ganglia Storage Based Authorization. Upgrade Oozie. When performing upgrade on SLES, you will see a message "There is an update candidate Hive security authorization may not be configured properly. The Oracle JDBC.jar file cannot be found. output-N.txt - the output from the command execution. /etc/rc.d/init.d/kadmin start, SLES 11 On the Server host, not automatically deleted after upgrade. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. in seconds. Ambari Blueprints provide an API to perform cluster installations. As part of installing HDP Stack with Ambari, HDP.repo and HDP-UTILS.repo files are generated and distributed to the cluster hosts based on the Base URL user Do. Make sure you have the correct components showing in HDFS. Excellent documentation skills. At the Use SSL* prompt, enter your selection. You use this log later to confirm the upgrade. Use the following instructions to prepare a non-default database for Ambari, Hive/HCatalog, Configuring Ambari to use a proxy server and have Internet access is not required. Make sure you have the correct FQDNs when specifying the hosts for your cluster. If the local system time of Check for any errors in the ZooKeeper logs (/var/log/hbase/) and restart the ZooKeeper to be up and listening on the network for the configured critical threshold, given For example, if you are using MySQL, copy your mysql-connector-java.jar. If you are upgrading a NameNode HA configuration, keep your JournalNodes running while See Managing Users and Groups for more information. The Ambari REST API provides access to HAWQ cluster resources via URI (uniform resource identifier) paths. Monitor the progress of installing, starting, and testing the service. Where is the Hive user name, is the Hive user password and is the Hive database name. After you select a service, the Summary tab displays basic information about the selected service. Each of the sections includes the specific sudo entries that should be placed Open the newconfig.json document and modify/add values in the properties object. To check if the Upgrade is progressing, check that the " \previous " directory has been created in \NameNode and \JournalNode directories. This step supports rollback and restore of the original state of HDFS data, if necessary. Accept the Oracle JDK license when prompted.

Components are sub-resources of services. /etc/init.d/iptables stopYou can restart iptables after setup is complete. The failure is due to misconfiguration or other setup errors. To preserve any custom logging properties after upgrading, for each service: Replace default logging properties with your custom logging properties, using Service Configs > Custom This can occur in environments where groups are managed in LDAP, and not on local Choose OK to confirm the change. interact securely with all hosts in the cluster. If your machine requires use of a proxy server for Internet access, you must configure and "This is required.". Retain a copy of the SSH Private Key on the machine from which you will run the web-based On the Ambari Server host: export the database: exp username/password@database full=yes file=output_file.dmp, Import the database: imp username/password@database ile=input_file.dmp.

After an hour all graphs will show a complete hour of data. version libraries will probably fail during the upgrade. total number of CPUs, see the alert definition. To delete these properties, execute the following for each property you found. Partial response can be used to restrict which fields are returned and additionally, it allows a query to reach down and return data from sub-resources. Valid values are :offset | "start", The ending page resource (inclusive). The bills of the user is passed via REST API to the mamBu back end. If this returns 200, go to Delete All JournalNodes. and processes required to continue the install. the user who submitted the application. Creates a root document for the new configuration. Browse to Ambari Web > Services, then choose Stop All in the Services navigation panel. The Tez Tasks Tab lets you see all tasks that failed For example, type: ssh For example, if you want Plan to remove Nagios and Ganglia from your cluster and replace with Ambari Alerts and Metrics. As noted in that section, you should remove and install on each host, only the components Append to the io.compression.codecs property key, the following value: com.hadoop.compression.lzo.LzoCodec,com.hadoop.compression.lzo.LzopCodec. You will use it later in the manual upgrade process. deployment and creation of views.The development and delivery of a View follows this process flow: Develop the View (similar to how you would build a Web application), Deploy the View into Ambari (using the Ambari Administration interface), Create and configure instances of the View (performed by Ambari Admins). checkboxes and clicking the grey Remove Selected button. Change the access mode of the.jar file to 644. chmod 644 /usr/share/java/postgresql-jdbc.jar, ambari-server setup --jdbc-db=postgres --jdbc-driver=/usr/share/java/postgresql-connector-java.jar, echo "CREATE DATABASE ;" | psql -U postgres where $version is the build number.
