Description
when hudi metadata is enabled, use different user to query table, the query will failed.
The user permissions of the temporary directory generated by DiskBasedMap are incorrect. This directory only has permissions for the user of current operation, and other users have no permissions to access it, which leads to this problem
test step:
step1: create hudi table with metadata enabled.
step1: create two user(omm,user2)
step2:
f1) use omm to query hudi table
DiskBasedMap will generate view_map with permissions drwx------.
2) then user user2 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
