[jira] [Created] (HIVE-17799) Add Ellipsis For Truncated Query In
Hive Lock
BELUGA BEHR created HIVE-17799:
----------------------------------
Summary: Add Ellipsis For Truncated Query In Hive Lock
Key: HIVE-17799
URL: https://issues.apache.org/jira/browse/HIVE-17799
Project: Hive
Issue Type: Improvement
Components: Hive
Affects Versions: 3.0.0
Reporter: BELUGA BEHR
Assignee: BELUGA BEHR
Priority: Trivial
[HIVE-16334] introduced truncation for storing queries in ZK lock nodes. This Jira is to add ellipsis into the query to let the operator know that truncation has occurred and therefore they will not find the specific query in their logs, only a prefix match will work.
{code:sql}
-- Truncation of query may be confusing to operator
-- Without truncation
SELECT * FROM TABLE WHERE COL=1
-- With truncation (will not find this query in workload)
SELECT * FROM TABLE
{code}
--
