> Clarifying the conditions in which audit logs record a query
> ------------------------------------------------------------
>
> Key: IMPALA-8768
> URL: https://issues.apache.org/jira/browse/IMPALA-8768
> Project: IMPALA
> Issue Type: Task
> Components: Docs
> Affects Versions: Impala 2.13.0, Impala 3.3.0
> Reporter: Vincent Tran
> Assignee: Alexandra Rodoni
> Priority: Minor
>
> Currently, Impala documentation highlights the following cases as operations
> which the audit logs will record:
> {noformat}
> Which Operations Are Audited
> The kinds of SQL queries represented in the audit log are:
> Queries that are prevented due to lack of authorization.
> Queries that Impala can analyze and parse to determine that they are
> authorized. The audit data is recorded immediately after Impala finishes its
> analysis, before the query is actually executed.
> The audit log does not contain entries for queries that could not be parsed
> and analyzed. For example, a query that fails due to a syntax error is not
> recorded in the audit log. The audit log also does not contain queries that
> fail due to a reference to a table that does not exist, if you would be
> authorized to access the table if it did exist.
> Certain statements in the impala-shell interpreter, such as CONNECT, SUMMARY,
> PROFILE, SET, and QUIT, do not correspond to actual SQL queries, and these
> statements are not reflected in the audit log.
> {noformat}
> However, based on[1], there is an unmentioned condition that the client must
> have issued at least one fetch for analyzed queries to be recorded in audit
> logs.
