The backend store of 'hugegraph' has not been initialized

@CPJ-data 需要先初始化后端，执行init-store.sh

CPJ-data commented 4 years ago

@javeme 已初始化的，0.10.4暂时是不是无法支持Cassandra存储后端，本地和服务器启动都不行？之前有提问这个问题，你的答复是使用tool中migrate命令迁移到0.9中去？

CPJ-data commented 4 years ago

@javeme 使用migrate命令在本地tools上执行，提示要安装sudo apt install python3-migrate，是否是这么操作的，如果不是具体该怎么执行操作。使用migrate进行hugegraph迁移，是不是0.10和0.9版本只要在本地下载就可以了，还是需要下载tools中进行执行操作，在官网的tools中也没有看到具体的详情介绍。感谢

javeme commented 4 years ago

@CPJ-data 升级是指将v0.9中的数据迁移到v0.10，两个版本的服务均需要正常运行。 升级之前，v0.9中有数据的，v0.10是空的图没有数据；通过migrate升级之后，把v0.9中的数据迁移到了v0.10中，v0.10有了全部的数据，并且可以把v0.9服务关闭了。

迁移需要执行命令 bin/hugegraph migrate

tools使用介绍

解压后，进入 hugegraph-tools 目录，可以使用bin/hugegraph或者bin/hugegraph help来查看 usage 信息。主要分为：
