[GitHub] [incubator-iotdb] aiping312 opened a new issue #1354: 在timeries下再创建子节点bug

URL: https://github.com/apache/incubator-iotdb/issues/1354
使用的是0.10版本。
在已有的timeries（root.ln.device1.s1）下再创建一个timeries，如root.ln.device1.s1.signal_value。在jdbc和cli下出现不同的结果。
1）JDBC下这么运行后 ，会造成服务卡死。打印的错误日志：
java.lang.ClassCastException: org.apache.iotdb.db.metadata.mnode.LeafMNode cannot be cast to org.apache.iotdb.db.metadata.mnode.InternalMNode
2）Cli下能成功执行，但是会将root.ln.device1.s1同级的timeries都屏蔽了，结果如下图：
IoTDB> show timeseries root.ln
+-------------+-----+-------------+--------+--------+-----------+
| timeseries|alias|storage group|dataType|encoding|compression|
+-------------+-----+-------------+--------+--------+-----------+
|root.ln.jgy.1| null| root.ln| FLOAT| GORILLA| SNAPPY|
|root.ln.jgy.2| null| root.ln| FLOAT| GORILLA| SNAPPY|
+-------------+-----+-------------+--------+--------+-----------+
Total line number = 2
It costs 0.022s
IoTDB> create timeseries root.ln.jgy.2.signal_value with datatype=FLOAT,encoding=GORILLA
IoTDB> show timeseries root.ln
+--------------------------+-----+-------------+--------+--------+-----------+
| timeseries|alias|storage group|dataType|encoding|compression|
+--------------------------+-----+-------------+--------+--------+-----------+
|root.ln.jgy.2.signal_value| null| root.ln| FLOAT| GORILLA| SNAPPY|
+--------------------------+-----+-------------+--------+--------+-----------+
这个是不是应该直接不允许在timeseries下再次创建timeseries

> 你用的具体是哪个版本啊，是rel/0.10分支么，可以给一个具体的复现步骤吗？
我再基于最新的0.10打包再试一次看看

在master版本，我们支持了timeseries下再次创建timeseries，即允许root.sg1.d0.s1.s2的出现，我测试了一下，master版本并未出现同级timeseries覆盖的现象。

在rel/0.10版本下，我们不支持timeseries下再次创建timeseries，我也做了相同的测试，但是创建时会有报错提示，并不会创建成功

是的，应该是不允许在timeseries下再次创建timeseries，我看一下，感谢反馈！
