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 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	Software Version
  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 based on OS and Software Requirements. Table 2 lists the components required by the Spark engine.

  Table 2 Required components

  Engine Using OmniMV	Required Components
  Spark	OS, JDK, Hadoop, Spark, Hive, and HDFS

  

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