> From a security perspective it would often be preferable pass the Azure 
> storage key via an env to the Flink Azure filesystem. Currently we only 
> support to set it in the Flink configuration [1].
> The least intrusive way, I think, would be to include a very simple 
> {{org.apache.hadoop.fs.azure.KeyProvider}} to flink-azure-fs-hadoop, which 
> reads the account key from an env variable called {{AZURE_STORAGE_KEY}}.
> It could then be enabled in the flink-conf.yaml via:
> {noformat}
> fs.azure.account.keyprovider.<account_name>.blob.core.windows.net: 
> org.apache.flink.fs.azurefs.<NewProviderClass>{noformat}
> [1]
