Final answer:
B) ResourceManager.The service ID running the processes on the Big SQL head node is B) ResourceManager, which is part of YARN in the Hadoop ecosystem.
Step-by-step explanation:
The service ID running the processes on the Big SQL head node is likely a reference to components within Hadoop, the distributed data processing system. The option 'Node Manager' corresponds to YARN (Yet Another Resource Negotiator), which is part of the Hadoop ecosystem, but does not specifically manage the running of processes on head nodes.
The 'ResourceManager' and 'NameNode' are both critical components of Hadoop. The correct answer to which service ID runs these processes is B) ResourceManager, typically associated with YARN, which manages resources and scheduling for user applications.
However, it is important to note that the 'NameNode' is the component that manages the metadata of the Hadoop Distributed File System (HDFS), but it is not generally responsible for running processes on the head node related to SQL operations.
