--------------------------------------
Summary: Non-SQLOperations lead to Web UI NPE
Key: HIVE-13099
URL: https://issues.apache.org/jira/browse/HIVE-13099
Project: Hive
Issue Type: Bug
Reporter: Mohit Sabharwal
Assignee: Mohit Sabharwal
To support display of live operations in the WebUI, we record SQLOperations (in
{{liveSqlOperations}}).
However, to support historic operations, we save all operations in
{{historicSqlOperations}}, including non-SQLOperations which do not have
display entries in liveSqlOperations.
This leads to a race condition depending on whether sessions use non-sql
operations. Reproduce-able by issuing a 'set' operation.

at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:98)
{code}
We should save only SQLOperations in historicSqlOperations.
