--------------------------------
Summary: Support read hive variables using the syntax like select
${hiveconf:select_time}
Key: FLINK-26371
URL: https://issues.apache.org/jira/browse/FLINK-26371
Project: Flink
Issue Type: Sub-task
Reporter: luoyuxia
In hive, it's allow to read hive variables using "${xxx}" in sql like "select
${hiveconf:select_time}".
But currently, such sql is not supported using hive dialect.
We're intented to support. To support it, following hive's implementation, we
can just substitute "${xxx}" with actual variable value to get clean sql.
