apache-spark - 在 Spark 2.4.0 中使用 spark.sql 的 Hive 表锁定信息抛出错误

Question

无法在 Spark 2.4.0 shell 中使用以下 SQL 查询来查询配置单元表锁定信息。

spark.sql("show locks dbName.tableName")

低于错误

scala> spark.sql("show locks dbName.tableName")
org.apache.spark.sql.catalyst.parser.ParseException:
Operation not allowed: show locks(line 1, pos 0)

== SQL ==
show locks dbName.tableName

但相同的查询在 Spark 1.6.0 中使用 hiveContext 工作

我的用例是在 Spark 2.4.0 的 spark 作业中获取有关 hive 表的锁定信息

有什么方法可以在 spark job 中获取表锁信息？

请参阅下面的链接。spark 2.4.0不支持锁

https://github.com/apache/spark/blob/branch-2.4/sql/catalyst/src/main/antlr4/org/apache/spark/sql/catalyst/parser/SqlBase.g4#L195

不支持的 HiveNativeCommands| kw1=显示 kw2=锁定

https://dbdb.io/db/spark-sql也在上面的博客上。并发控制部分说，它不支持锁。
