Exception Resolution 1, 401 Unauthorized:error Failed to connect to newly launched supervisor. Agent would exit this is because after the agent is started on the master node, and the agent SCP to the other nodes, the first time you start the agent, it will generate a UUID, the path is:/opt/cm-xxx/lib/cloudera-scm-agent/uuid, In this way, each machine on the agent's UUID is the same, there will be a situation of disorder. Solution: Delete all files
I just started to play with Cloudera Manager 5.0.1 and a small fresh setup cluster. It has six datanodes with a total capacity of 16.84 TB, one Namenode and another node for the Cloudera Manager and other S Ervices. From start on, I is wondering how to start the HDFS balancer.
Short answer:
To run the balancer your need to add the balancer role to any node in you cluster!
I'll show you the few simple steps
Why does Cloudera need to create a Hadoop security component Sentry?1. Big Data Security System
To clarify this issue, we must start from four levels of the big data platform security system: Peripheral Security, data security, access security, and access behavior monitoring, as shown in;
Peripheral Security technology refers to the network security technology mentioned in the traditional sense, such as firewall and login authentication;
