Installation Node Requirements

Check that the configuration of each node meets the OmniMV installation requirements. Before compiling the source code, install GCC/G++, make, CMake, and Glibc on each node and ensure that they meet the version requirements. Before installing OmniMV, prepare the cluster environment and those components required for installing the Spark/ClickHouse engine based on the OS and software requirements.

• Before using the source code for compilation, install GCC/G++, Make, CMake, and glibc on each node. The version requirements are listed in Table 1.

  Table 1 Software required for source code compilation

  Software Name	Version Requirement
  GCC/G++	7.3.0
  Make	4.2.1 or later
  CMake	3.13.4 or later
  glibc	2.25 or later

• Before installing OmniMV, install related components in the cluster environment by referring to OS and Software Requirements. Table 2 lists the components required by Spark and ClickHouse.

  Table 2 Mandatory components

  Involved Engine	Required Components
  Spark	OS, JDK, Hadoop, Spark, Hive, and HDFS
  ClickHouse	OS, JDK, ZooKeeper, and ClickHouse

  

  You can select a cluster mode based on the application scenario requirements. The secure mode (Kerberos) is recommended if the storage mode is HDFS.
