[Impala-ASF-CR] IMPALA-9977: Remove duplicate Ranger audit log entries for ALTER events

IMPALA-9977: Remove duplicate Ranger audit log entries for ALTER events

This JIRA could be considered as a follow-up to IMPALA-9625, where we
converted the name of a TAccessEvent to lowercase to avoid duplicate
audits in the Set used to maintain the collected TAccessEvent's so that
there will not be duplicate TAccessEvent's in the file specified by the
flag of "-audit_event_log_dir" when Impala is started.

However, the patch for IMPALA-9625 only considered the audits that are
exported to the specific file mentioned above but not the
PrivilegeRequest's that will be processed by Ranger which in turn would
produce the corresponding audit log entries. Therefore, the
fully-qualified table name that is provided when
Analyzer#registerPrivReq() is called in Analyzer#getTable() is not
necessarily in lowercase, resulting in duplicate AuthzAuditEvent's
stored in the corresponding RangerBufferAuditHandler because the
full table names returned from registerAuthAndAuditEvent() and
getTable() differ. Refer to IMPALA-9625 for more details.

To resolve the inconsistencies, this patch converts the arguments of
database and table names to lowercase when
PrivilegeRequestBuilder#onTable() is building the corresponding
PrivilegeRequest, which will later be added to the Set of
PrivilegeRequest's for Ranger to process.

Testing:
- Added an FE test in RangerAuditLogTest.java to make sure no duplicate
  Ranger audit log entries are produced.

Not a problem at all. :-) This patch is still being tested by a Jenkins job to make sure there is no regression after applying the proposed changes. Will update you on this after the result of testing is known.

Thanks Quanlong for the prompt reply! I actually have not checked this for all other types of statements. I think it may be good to create a follow-up JIRA to investigate this.

What I am sure of now is that for an existing table, the registration of PrivilegeRequest for ALTER would occur twice. One in Analyzer#registerAuthAndAuditEvent() (https://github.com/apache/impala/blob/master/fe/src/main/java/org/apache/impala/analysis/Analyzer.java#L3155-L3161) and the other in Analyzer#getTable() (https://github.com/apache/impala/blob/master/fe/src/main/java/org/apache/impala/analysis/Analyzer.java#L2860-L2872).

On the other hand, for a non-existing table, there could be 1 or 2 registrations for ALTER depending on the size of 'rawPath' (https://github.com/apache/impala/blob/master/fe/src/main/java/org/apache/impala/analysis/Analyzer.java#L734-L752).

Does this only happen on ALTER events? Or other queries have uppercase table names also suffer the same issue?
