Compatibility with Other Patches


Impact of Patch Installation

  • During the installation of the MRS patch, MRS Manager is restarted, and Hadoop, HDFS, Hive, Spark, and related dependent services are restarted in rolling mode. During the restart of MRS Manager, services are temporarily unavailable but services are not interrupted during the rolling restart.
  • After installing the MRS patch, you need to download and install all clients again, including the original clients of the Master node and the clients used by other nodes of VPC (that is, the clients that you set up).
    • You are advised to back up the old clients before reinstalling the new ones.
    • If you have modified client configurations based on the service scenario, modify them again after reinstalling the clients.
