Fix problem: For the same column, there are concurrent drop index request and build index request, if build index obtain lock before drop index, build a new index file, but when drop index request execute, link file not contains all index files for the column, that lead to new index file is missed. Based on the above questions, use index id instead of column unique id to determine whether a hard link is required when do build index
