Thanks Yun,
I make it work, but now I want to set appropriate config programmatically.
I can set state.checkpointing.dir by:
val fsStateBackend = new FsStateBackend(new
URI("wasb://<your-container>@$<your-azure-account>.blob.core.windows.net/<object-path>"))
env.setStateBackend(fsStateBackend.asInstanceOf[StateBackend])
But, I can’t update configuration to add credentials
fs.azure.account.key.<account_name>.blob.core.windows.net: <azure_storage_key>
Because getConfiguration is a private method. Any suggestions?
