> ABFS: MsiTokenProvider doesn't retry HTTP 429 from the Instance Metadata
> Service
> --------------------------------------------------------------------------------
>
> Key: HADOOP-17377
> URL: https://issues.apache.org/jira/browse/HADOOP-17377
> Project: Hadoop Common
> Issue Type: Bug
> Components: fs/azure
> Affects Versions: 3.2.1
> Reporter: Brandon
> Priority: Major
> Labels: pull-request-available
>
> *Summary*
> The instance metadata service has its own guidance for error handling and
> retry which are different from the Blob store.
> [https://docs.microsoft.com/en-us/azure/active-directory/managed-identities-azure-resources/how-to-use-vm-token#error-handling]
> In particular, it responds with HTTP 429 if request rate is too high. Whereas
> Blob store will respond with HTTP 503. The retry policy used only accounts
> for the latter as it will retry any status >=500. This can result in job
> instability when running multiple processes on the same host.
> *Environment*
> * Spark talking to an ABFS store
> * Hadoop 3.2.1
> * Running on an Azure VM with user-assigned identity, ABFS configured to use
> MsiTokenProvider
> * 6 executor processes on each VM
> *Example*
> Here's an example error message and stack trace. It's always the same stack
> trace. This appears in logs a few hundred to low thousands of times a day.
> It's luckily skating by since the download operation is wrapped in 3 retries.
