Aiming at the problem of absolute full discretionary management of metadata based on HDFs cloud storage platform, this paper proposes a metadata autonomous organization model ASOM, through analyzing the interaction between Datanode and Namenode, Asom design and implement metadata sub service, The Datanode metadata information in HDFs is directly interacting with the metadata sub server, and the mapping relationship between file and block, block and Datanode is processed by the metadata sub server. By analyzing and compiling the HDFs source code and building the prototype system, the test results show that: The necessary security isolation of metadata in Namenode ensures user's control and management of metadata, which can effectively avoid the potential malicious operation and security hidden trouble of the platform administrator.
