[0087] Only the differences between this embodiment and the specific embodiment 1 are described below, and the similarities are not repeated here. Figure 4-5 They are another preferred principle schematic diagram and flow diagram of the hot and cold data analysis method of the embodiment of the present invention, combined with reference Figure 4-5 As shown, the difference between the cold and hot data analysis method of this embodiment and the specific embodiment 1 is:

[0088] Considering that only the neural network algorithm model LSTM is used to divide the hot and cold data, there may be a problem that some files have not been accessed for a long time from the current time point but are mistakenly marked as 1. Therefore, the hot and cold data analysis step S2 also includes:

Abstract

The invention provides a cold and hot data analysis method and system. The cold and hot data analysis method comprises the following steps: a file data information acquisition step: analyzing a metadata node NameNode and an audit log AudiLog of a Hadoop distributed file system HDFS to obtain data information of a file in the HDFS; and a cold and hot data analysis step for analyzing the data information of the file in the HDFS by using a neural network algorithm model LSTM, and dividing the file of the HDFS into cold data and hot data by taking the data information as a reference. According tothe scheme, the file data information is analyzed through the neural network algorithm model LSTM to obtain the cold and hot data; and meanwhile, a cache elimination algorithm LRU is utilized to improve the accuracy of analyzing the cold and hot data, data support for data cleaning is provided for a service group and operation and maintenance personnel, the efficiency and accuracy of data cleaningare improved, and the personnel cost is saved.

Description

technical field [0001] The invention belongs to the technical field of big data, and in particular relates to a cold and hot data analysis method and system. Background technique [0002] Hadoop Distributed File System (HDFS for short) refers to a distributed file system designed to run on commodity hardware. HDFS can provide high-throughput data access and is very suitable for applications on large-scale data sets. [0003] In HDFS, NameNode is a metadata node and DateNode is a data node. NameNode maintains the mapping table of files and data blocks and the mapping table of data blocks and data nodes; DataNode stores real data. The metadata node NameNode manages the namespace of the file system. It maintains the file system tree and all files and directories in the entire tree. These information are stored in two files, one is the metadata image file FsImage, and the other is the metadata operation Log EditLog. Among them, the metadata image file FsImage saves the lates...
