HiveContext：无法通过JDBC客户端查看临时表

Question

  

在pyspark，

注册临时表

from pyspark import HiveContext
sqlContext = HiveContext(sc)
df = sqlContext.sql("select * from test").collect()
df.registerTempTable("testing")
sqlContext.sql("show tables").show()
+--------------------+-----------+
|           tableName|isTemporary|
+--------------------+-----------+
|             testing|       true|
|               check|      false|
+--------------------+-----------+

我可以查看临时表＆＃34;测试＆＃34;来自pyspark

我启动了spark thrift服务器

启动JDBC客户端并连接到spark thrift服务器，

$ ./bin/beeline
beeline> !connect jdbc:hive2://ip:10000
Connecting to jdbc:hive2://ip:10000
Enter username for jdbc:hive2://ip:

我无法查看临时表。 有什么东西我不见了吗？

Answer 1

临时表只能在您当前的会话中存活。这意味着您通过beeline的新会话无法看到临时表testing。
