@n3nash Looks like you shepherded the change with gary :). I don't see #795
actuallly make this path change.
Instead of fixing perms (which may not work actually, based on permissions,
like you can have write perms, but not to do chmod), can we create an unique
folder like `/tmp/hudi_fsview_map-<uuid>` . This should be totally backwards
compatible to do. thoughts?

> 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
