The user permissions of the temporary directory(default value is /tmp/view_map) generated by DiskBasedMap are incorrect. This directory only has permissions for the user who execute query firstly, and other users have no permissions to access it , which leads to this problem test step： step1: create hudi table with metadata enabled. step2： create two users（omm，user2） to query the table which created by step1 step3： 1）using omm user to query hudi table DiskBasedMap will generate view_map with permissions drwx------. 2）using user2 user to query hudi table now user2 has no right to access view_map which created by omm, the exception will throws: **org.apache.hudi.exception.HoodieIOException: IOException when creating ExternalSplillableMap at /tmp/view_map** ## Brief change log *(for example:)* - *Modify AnnotationLocation checkstyle rule in checkstyle.xml* ## Verify this pull request Manually verified the change ## Committer checklist - [ ] Has a corresponding JIRA in PR title & commit - [ ] Commit message is descriptive of the change - [ ] CI is green - [ ] Necessary doc changes done or have another open PR - [ ] For large changes, please consider breaking it into sub-tasks under an umbrella JIRA. -- This is an automated message from the Apache Git Service.
