Description

This task is to revisit the configurations to make SPS service modes - internal/external/none

• internal : represents SPS service will be running with NN
• external: represents SPS service will be running outside NN
• none: represents the SPS service is completely disabled and zero cost to the system.

Proposed configuration dfs.storage.policy.satisfier.mode item in hdfs-site.xml file and value will be string. The mode can be changed via reconfig command.
