DataStax DevCenter架构窗口始终为空

时间：2015-09-08 11:07:53

标签： cassandra

成功连接到Cassandra后，创建了几个键空间和表，DevCenter Schema窗口突然变空。

即使在重新启动DevCenter并重新安装DevCenter（包括删除用户主目录下的.devcenter目录）几次之后，它也没有显示任何内容并保持空白。

在DevCenter default_1.cql窗口“in keyspace”下拉列表中，我可以看到下拉列表中的键空间

使用cqlsh我可以在那里看到所有的键空格和表。

环境信息：在最新的Mac OS上运行DevCenter 1.4.1，在最新的Centos7上运行Cassandra 2.2.1。

关于可能是什么原因以及如何解决它的任何想法？

感谢。

在DevCenter错误日志中找到以下堆栈跟踪（关于DevCenter - ＆gt;安装详细信息 - ＆gt;查看错误日志）

答案 0 :(得分：1)

从堆栈跟踪中，看起来DevCenter用于连接到Cassandra的java驱动程序在被询问它的数据类型时无法找到用户定义的类型字段“STATUS_ID”。

Caused by: java.lang.IllegalArgumentException: STATUS_ID is not a field defined in this definition
at com.datastax.driver.core.UserType.getFieldType(UserType.java:165)
at com.datastax.devcenter.schema.SchemaInitializer.getDataTypeMapping(SchemaInitializer.java:611)

这不应该发生，因为直接从java驱动程序检索字段名称列表。

我能够重现这个问题，我认为根本原因是java驱动程序的区分大小写问题，尽管DevCenter也应该更好地处理这个问题。我为java驱动程序提交了JAVA-962。

感谢您提出/报告此事。
