[jira] [Comment Edited] (FLINK-31310) Force clear directory no matter what situation in HiveCatalog.dropTable

    [ https://issues.apache.org/jira/browse/FLINK-31310?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17696460#comment-17696460 ]

----------------------------------------------------------------

[~lzljs3620320], the `dropTable` interface is invoked after `getTable`, therefore if no tale in hive, the `dropTable` could not be invoked, because there is a check whether table exist in `getDataTableSchema`. The exist situation occurs in the `getTable`, not in `dropTable`.

IMO, when no table in hive, users could use the FileSystemCatalog to drop the table and clear table directory and HiveCatalog only drops the table in Hive and clear table directory via hive metastore client.
