This paper designs a Hadoop cloud platform for electronic archives information management, and designs its functional modules. The pre-processing and eigenvalue extraction of electronic archives data can be realized through Mapreduce programming model, and the data can be stored in an infinitely expanded base for call at any time. During the process of experiment, the experimental environment is established and configured to analyze the relevant data and perform data pre-processing experiments. The processed data is stored in HBase instance, which basically achieves the expected functions. At the same time, the experiment shows that the archive-Cloud platform based on Hadoop can meet the basic requirements of electronic archives data preprocessing and data storage.
