--------------------------------------
Summary: SBAP errors on null partition being passed into partition
level authorization
Key: HIVE-5485
URL: https://issues.apache.org/jira/browse/HIVE-5485
Project: Hive
Issue Type: Bug
Components: Authorization
Affects Versions: 0.12.0
Reporter: Sushanth Sowmyan
Assignee: Sushanth Sowmyan
SBAP causes an NPE when null is passed in as a partition for partition-level
authorization.
Personally, in my opinion, this is not a SBAP bug, but incorrect usage of
AuthorizationProviders - one should not be calling the column-level authorize
(given that column-level is more basic than partition-level) function and pass
in a null as the partition value. However, that happens on code introduced by
HIVE-1887, and unless we rewrite that (and possibly a whole bunch more(will
need evaluation)), we have to accommodate that null and appropriately attempt
to fall back to table-level authorization in that case.
The offending code section is in Driver.java:685
{code}
678 // if we reach here, it means it needs to do a table authorization
679 // check, and the table authorization may already happened because
of other
680 // partitions
681 if (tbl != null && !tableAuthChecked.contains(tbl.getTableName())
&&
682 !(tableUsePartLevelAuth.get(tbl.getTableName()) ==
Boolean.TRUE)) {
683 List<String> cols = tab2Cols.get(tbl);
684 if (cols != null && cols.size() > 0) {
685 ss.getAuthorizer().authorize(tbl, null, cols,
686 op.getInputRequiredPrivileges(), null);
687 } else {
688 ss.getAuthorizer().authorize(tbl,
op.getInputRequiredPrivileges(),
689 null);
690 }
691 tableAuthChecked.add(tbl.getTableName());
692 }
{code}
