Pradeep Kamath commented on HIVE-1476:
--------------------------------------
A proposal for the solution:
Instead of the Metastore code creating the directories why not have
HiveMetastoreClient create it in createTable() after the table is created -
i.e. it can do a getTable().getSd().getLocation() and perform wh.mkdirs() on
that path. We could do the same thing with addPartition() and other places
where needed. The issue with this is it still breaks direct thrift clients. So
a compromise is to use a conf variable - "strict.owner.mode" - if this is set
to true on the server, dirs will not be created and they will be created on the
client (both client and server should have the same value (true or false). In
installations where there are thrift clients, this can be set to false till the
point the clients are ready to create the dirs themselves.
HiveMetaStoreClient needs to change to read this conf variable and create dirs
if it is set to true. This directory creation/deletion is relevant to create
table/drop table/add partition/alter table/alter partition I think.
> Hive's metastore when run as a thrift service creates directories as the
> service user instead of the real user issuing create table/alter table etc.

> URL: https://issues.apache.org/jira/browse/HIVE-1476
> Project: Hadoop Hive
> Issue Type: Bug
> Affects Versions: 0.6.0, 0.7.0
> Reporter: Pradeep Kamath
>
> If the thrift metastore service is running as the user "hive" then all table
> directories as a result of create table are created as that user rather than
> the user who actually issued the create table command. This is different
> semantically from non-thrift mode (i.e. local mode) when clients directly
> connect to the metastore. In the latter case, directories are created as the
> real user. The thrift mode should do the same.
