afero fs

It is necessary to record the contact with FS for so long. The previous article introduced the format of dot in the FS topology description file. Today we will introduce the format of the FS output file. For example, below is a record of the output file of the d node, that is, the record of a stream passing through D. Textexport D 1.035154 1.035154 1.175314 10.1.

To continue our experiment, the previous steps can be returned to the first article: http://gshao.blog.51cto.com/3512873/1788027----------------------------------I'm a slightly soiled mid-line-------------------------------------The approximate idea steps are as follows:1. Add a UPN to configure the user's UPN suffix (this is related to whether or not your domain name is consistent, if you miss this step directly)2. Application certificate (public network) 3. Install the AD

Btrfs (Btree FS) file system:is a copy to write file system developed by Oracle in 2007 to enable large-scale storage of missing pools, snapshots, checksums and cross-device access issues in the file system.Btrfs Features:1.btrfs can consist of multiple underlying physical volumes, RAID enabled, online Add, remove, modify2.

Use async and await asynchronous operations to solve the problem of fs module asynchronous read/write and synchronization results in node. js, asyncnode. js Async await solves the asynchronous problem. These two keywords are proposed by es7. Therefore, the node and browser versions are improved in testing. Async await operations are implemented based on promise The async await keywords are used together. If they are used separately, an error is return

Recently, the data format stored in HDFS is incorrect because the data contains \ r \ n characters, which are not taken into account during program processing. Historical data is about one year old. You need to delete the wrong data or duplicate data to keep the correct data. Pig is used in the project for data processing, so I wrote a UDF Java class to filterFor the wrong data, save the wrong data and the correct data separately, and then write the schema and number of the following script stat
