Cassandra 升级后DSE Gremlin架构错误（Datastax 5.0至5.1）

在将Datastax Cassandra从5.0版升级到5.1版之后，我们得到了 如下所述，连接到现有键空间时出现gremlin错误，而在图形中创建新键空间并通过gremlin连接时没有问题

$gremlin> :remote config alias g chat_bot.g
==>g=chat_bot.g
$gremlin> schema

1） 注入构造函数时出错

没有人可以帮忙吗？

您是否尝试过

schema.descripe（）

？是的。同样的错误。您可以详细说明您使用或遵循的确切升级过程吗？另外，您是否在节点

/system.log

中看到任何错误？我们已在3个节点中逐一完成了下面提到的步骤。。。。nodetool flush nodetool upgradessstables java-版本nodetool drain/etc/init.d/dse stop sudo apt get update sudo apt get install dse full/etc/init.d/dse start nodetool upgrades表尾/var/log/cassandra/system.log具有输出
