无法在spark 2.4.0 shell中使用以下sql查询查询配置单元表锁信息。
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

但同样的查询在spark 1.6.0和hivecontext中也可以使用
我的用例是在spark2.4.0中获取spark作业中关于配置单元表的锁信息
如果有什么办法,我可以得到表锁信息在Spark作业?

请参见下面的链接。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
不支持本地命令| kw1=显示kw2=锁
https://dbdb.io/db/spark-sql 在上面的博客上也是。并发控制部分说,它不支持锁。
