The environment is implemented under vmware7, and the operating system is fedora14 (Nima 12 and 13 have all tried it. Due to Yum source problems, some RPM packages are searched for by themselves, which cannot afford to hurt ..) Talk less, work! 1. Ensure that your yum source is up-to-date and availableThis saves a lot of trouble. For example, Pax, patch, and Python-setuptools are all dependent on the cdh3 component. 2. Install JDK and JRE.

information to the central storage system. Kafka provides two consumer interfaces, one of which is low level. It maintains a connection to a broker and the connection is stateless, that is, every time pull data is obtained from the broker, the offset of the broker data must be told. The other is the high-level interface, which hides the details of the broker and allows the consumer to push data from the broker without worrying about the network topology. More importantly, for most log systems,

, this mechanism implements the simple Paxos protocol to ensure the consistency of distributed logs. There are two roles in the design: 1. the node where the JournalNode actually writes logs is responsible for storing logs to the underlying disk, which is equivalent to the acceptor in the paxos protocol. 2. QuorumJournalManager runs in NameNode. It is responsible for sending log write requests to all journalnodes and executing the write Fencing and log synchronization functions, which is equival

Recently, I joined Cloudera. Before that, I have been working in computational biology genomics for almost 10 years. My analysis is mainly based on the Python language and its great scientific computing stack. However, most ApacheHadoop ecosystems are implemented in Java and are also prepared for Java, which makes me very annoyed. So, my head Recently, I joined Cloudera. Before that, I have been working in

If you are using Kafka to distribute messages, there may be exceptions or other errors in the process of data processing that can result in loss or inconsistency. This time you may want to Kafka the data through the new process, we know that Kafka by default will be saved on disk to 7 days of data, you just need to Kafka a topic of the consumer offset to a certain value or a minimum value, You can get the consumer to start spending from the point you set.Querying the range of topic offsetUse the
