Tags: HBase is a distributed, column-oriented, open-source database that comes from the Google paper "Bigtable: A distributed storage system of structured data" written by Fay Chang. Just as BigTable leverages the distributed data store provided by the Google File system, HBase provides bigtable-like capabilities on top of Hadoop. HBase is a sub-project of the Apache Hadoop project. HBase differs from the general relational database, which is a database suitable for unstructured data storage.

To add a new host node to the CDH5 clusterStep one: First you have to install the JDK in the new host environment, turn off the firewall, modify SELinux, NTP clock synchronization with the host, modify the hosts, configure SSH password-free login with the host, ensure that Perl and Python are installed.Step two: Upload the Cloudera-manager file to the/OPT directory and modify the agent configuration file:Vi/opt/cm-5.0.0/etc/cloudera-scm-agent/config.i

Tip: If you're not aware of Hadoop, you can view this article on the Hadoop ecosystem, which allows us to get an overview of the usage scenarios for tools in Hadoop and Hadoop ecosystems. To build a distributed Hadoop cluster environment, here are the detailed steps to use CDH5.First, hardware preparationBasic configuration: Operating system 64 guests Cpu (Intel) Intel (R) I3 processor Memory 8.00 GB (MH

Modify the IP address, hostName, and cdh5hostname of the host node in the cdh5 cluster.Preface When using the cdh cluster, it is inevitable that the node IP address or hostName changes due to some irresistible reasons, and the cm monitoring interface cannot complete these tasks, however, cm stores all host information in the hosts table of the postgresql database, Now let's modify the hosts to complete this operation.Step 1: Disable the service 1.
