gained in this practice: Know the Hadoop source file name, quickly find the file to write the program when directly looking at the Hadoop related source debug program, you can directly enter the source code to view and track the run Recommendation Index: ★★★★ Recommended reason: Through the source code can help us to better understand Hadoop, can help us solve complex problems 3. Proper use of compression algorithms The following table of information refers to the

There are many versions of Hadoop, and here I choose the CDH version. CDH is the Cloudera company in Apache original base processed things. The specific CHD is:http://archive-primary.cloudera.com/cdh5/cdh/5/The version information is as follows:Hadoop:hadoop 2.3.0-cdh5.1.0jdk:1.7.0_79maven:apache-maven-3.2.5 (3.3.1 and later must be above JDK1.7)protobuf:protobuf-2.5.0ant:1.7.11.

because the node servers in the cluster are automatically assigned IPS through DHCP, the IP is not changed in principle, because a fixed IP address has been assigned to the MAC address at boot time, unless the MAC address is changed. Coincidentally, yesterday morning sweeping aunt to a master node server because of wiping the table and the network cable to rip off, and so I found that the node is not connected to the time, re-plug the network cable after the result of the IP changed. Think of a

follow Unix mode? Yes, Hadoop also has a "conf" directory under UNIX use cases. 7. What directory is Hadoop installed in? Cloudera and Apache use the same directory structure, and Hadoop is installed in cd/usr/lib/hadoop-0.20/. 8. the port number for Namenode, Job Tracker, and task tracker is. Namenode,70;job Tracker,30;task tracker,60. 9. What is the core configuration of Hadoop? The core configuration of Hadoop is done through two XML files: 1,hado

recommend that you install Cloudera Manager on a Hadoop cluster, which provides real-time statistics on CPU, hard disk, and network load. (Cloudera Manager is a component of Cloudera Standard Edition and Enterprise Edition. The Enterprise Edition also supports rolling upgrade.) After Cloudera Manager is installed, the

SQOOP is an open-source tool mainly used for data transmission between Hadoop and traditional databases. The following is an excerpt from the SQOOP user manual. Sqoopis a tool designed to transfer data between Hadoop and relational databases. you can use Sqoop to import data from a relational database management system (RDBMS) such as MySQL or Oracle into the Hadoop Distributed File System (HDFS), transform the data in Hadoop MapReduce, and then export the data backinto an RDBMS. SQOOP is an ope

The program that has been developed Hadoop2.2.0 with Maven before. Environment changed to CDH5.2 after the error, found that Maven relies on the library problem. have been using http://mvnrepository.com/to find Maven dependencies before. But such sites can only find generic maven dependencies, not including CDH dependencies. Fortunately Cloudera provides a CDH dependency:Http://www.cloudera.com/content/cloudera
