由于endianness不匹配,无法使用flink rocksdb状态后端

我的flink作业读取一个kafka主题,并将数据存储在rocksdb状态后端,以便使用可查询状态。我可以运行作业并查询本地计算机中的状态。但是在集群上部署时,我得到以下错误:

我已经尝试在集群级别和作业级别设置rocksdb状态后端。当它设置为作业级别时,我将它作为着色依赖项提供。我也尝试过在主机集群机上编译代码。我在所有情况下都会犯同样的错误。

如何解决此错误?

通过以下方式解决问题:
克隆青蛙。
从此提交中应用rocksdb修补程序。
make rocksdbjava 在目标平台上。
添加结果 rocksdbjni-<version-platform>.jar 作为本地maven依赖项
在目标平台上建造flink frocksdbjniflink-statebackend-rocksdb/pom.xml 指着当地的mavenjar。
注意:此修补程序已在的最新版本中提供 rocksdb . 一次 frocksdb 已更新为的当前版本 rocksdb ,则不应出现此问题。
