tao meng created HUDI-2090:
------------------------------

             Summary: when  hudi metadata is enabled,  use different user to query table, the query will failed
                 Key: HUDI-2090
                 URL: https://issues.apache.org/jira/browse/HUDI-2090
             Project: Apache Hudi
          Issue Type: Bug
          Components: Common Core
    Affects Versions: 0.8.0
            Reporter: tao meng
            Assignee: tao meng
             Fix For: 0.9.0


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
