------------------------------------------
Summary: Add queryid in QueryLifeTimeHookContext
Key: HIVE-26095
URL: https://issues.apache.org/jira/browse/HIVE-26095
Project: Hive
Issue Type: New Feature
Components: Hooks
Reporter: Stamatis Zampetakis
Assignee: Stamatis Zampetakis
Fix For: 4.0.0-alpha-2
A
[QueryLifeTimeHook|https://github.com/apache/hive/blob/6c0b86ef0cfc67c5acb3468408e1d46fa6ef8024/ql/src/java/org/apache/hadoop/hive/ql/hooks/QueryLifeTimeHook.java]
is executed various times in the life-cycle of a query but it is not always
possible to obtain the id of the query. The query id is inside the
{{HookContext}} but the latter is not always available notably during
compilation.
The query id is useful for many purposes as it is the only way to uniquely
identify the query/command that is currently running. It is also the only way
to match together events appearing in before and after methods.
The goal of this jira is to add the query id in
[QueryLifeTimeHookContext|https://github.com/apache/hive/blob/6c0b86ef0cfc67c5acb3468408e1d46fa6ef8024/ql/src/java/org/apache/hadoop/hive/ql/hooks/QueryLifeTimeHookContext.java]
and make it available during all life-cycle events.
