Abstract

The invention discloses a method for preventing mis-deleting of data in HBase. The method comprises the following steps: setting and storing the storage file of deleted data file in an HDFS catalogue according to user operation; setting a monitoring time period, and monitoring whether the cache folder of the Hbase in the HDFS catalogue has a newly increased data file according to the time period; if so, storing the newly increased data file to the storage file. The method can prevent mis-deleting of data in the HBase. The invention further discloses a system for preventing mis-deleting of data in HBase.

Description

technical field [0001] The invention relates to the technical field of data security, in particular to a method and system for preventing data from being deleted by mistake in HBase. Background technique [0002] HBase is a distributed, column-oriented open source database. All data files in HBase are stored on Hadoop's distributed file system HDFS. HBase supports horizontal expansion of data nodes, and the storage capacity also depends on the number of nodes. In a production environment, the data volume of HBase tables is generally relatively large, and the recovery cost of accidental deletion is relatively high. Although Hadoop's distributed file system HDFS has a recycle bin policy, it does not take effect for Hbase table data. [0003] Once the operation of deleting the Hbase table is performed, the metadata of Hbase will be deleted first, and then the data of each region (data partition) will be moved to a folder called "archive". Finally, the master main thread of Hb...
