Zookeeper Background] Today, a friend asked me this question. Their OA application databases and interface databases are deployed on two different servers. The interface server is mainly responsible for integrating with third-party systems. The third-party system calls the interface to create OA documents, and the OA system approves the documents. After the OA approval is completed, the interface of the interface server is called, OA returns approved transfer records and attachments to a third-p

Collector, usually known as a thief Program It is mainly used to capture others' webpage content. It is not difficult to create a collector, that is, to remotely open the webpage to be collected, and then use a regular expression to match the required content, as long as there is a little basis for a regular expression, you can make your own collectors. I developed a novel serialization program a few d

Official documentation is not detailed operation also a little problem, so the operation is recorded as follows.Operating system Environment:CentOS 5.8Python 2.4.3Create a collector and so on, don't say it here, see Official document: http://blog.jiankongbao.com/?p=1285First, because my Python is 2.4, you will install Hashlib, cTYPES, Simplejson inside the library, the specific operation is as follows:Hashlib Source InstallationFirst, install Python-d

Garbage collection: Frees objects that are no longer referenced by any variablesGarbage collector: A program that specifically records the number of references to an object and reclaims objects that are no longer referenced.Garbage collector and main program are executed in the background in parallelThe garbage collector creates a reference counter (counter) for

God Arrow Hand Cloud Collection:A new cloud online intelligent crawler/collector, based on the god-Archer Distributed Cloud Crawler framework, to help users quickly obtain a large number of normalized Web page data. Support the collection and automatic posting of articles, forum posts and replies, product information and comments, forms and other web site data.Features: Direct access to proxy IP. No need to set up to avoid the problem caused by the li

garbage collector is concerned with this part of the memory.Heap memory for this large number of object instances, the garbage collector first to determine which of these objects are "alive" and which are "dead"Reference counter AlgorithmAdds a reference counter to the object, which is incremented by 1 whenever it is referenced, minus one when the reference is lost. At any moment, the calculator value of 0

This morning the cluster space is full, mobile Ambari Metrics collector Log Directory after the service can not start, the log is as follows:Java.net.ConnectException:Connection refused at Sun.nio.ch.SocketChannelImpl.checkConnect (Native Method) At Sun.nio.ch.SocketChannelImpl.finishConnect (Socketchannelimpl.java:712) at Org.apache.zookeeper.ClientCnxnSocketNIO.doTransport (Clientcnxnsocketnio.java:361) at Org.apache.zookeeper.clientcnxn$sendthread.

in their reference counters are not 0, the garbage collector will never reclaim them. Accessibility analysis algorithmBy using a series of objects called "GC Roots" as starting points, the search is traversed by a path called a reference chain (Reference Chain), proving that the object is not available when an object is connected to a GC Roots without any reference chain. For example, objects Object5, OBJECT6, and Object7 are associated with each o

Collector, usually called the Thief program, is mainly used to crawl other people's web content. On the production of the collector, it is not difficult to open the Web page to be collected remotely, and then use regular expressions will need to match the content, as long as a little bit of regular expression of the basis, can make their own collector to. A few

, the garbage collector will never reclaim Objectobj = new Object (); The corresponding object such as Obj.equels (NewObject ()) can be obtained directly through the objective lens. And so the Obj object is a strong reference to the subsequent newobject, and only if the obj reference is released, the object will be released, which is also the encoding form we often use. 2, soft reference Must be referenced and reclaimed before memory overflows, and ca

Lucene's collector is an advanced function that involves detailed steps in the search process. By customizing collector, you can change the default search, or collect information about hit documents at this stage. The following example shows how to customize a collector and how to collect data in a custom collector.
