HiveMetaStore-based authority control method

The invention relates to the technical field of authority control, in particular to an authority control method based on HiveMetaStore, which comprises the following steps: submitting metadata information in the HiveMetaStore to Hiveserver 2 to output optimized data, and inputting the optimized data into an authority check plug-in to perform matching verification with a strategy file; when the matching verification is passed, returning the corresponding metadata information to the input end; obtaining verification passing times of authority verification in a plurality of verification periods; judging the comprehensiveness of the authority control based on the variance of the verification passing times of the authority verification; if it is judged that the comprehensiveness does not meet the requirement, the number of concurrent synchronous connections of the permission check plug-ins is adjusted; if it is determined that the stability does not meet the requirement, the cache refresh frequency of the strategy
