[GitHub] [spark] mohamadrezarostami opened a new pull request #34910: Fix bug in report driver status
mohamadrezarostami opened a new pull request #34910:
URL: https://github.com/apache/spark/pull/34910
### What changes were proposed in this pull request?
After an improvement in SPARK-31486, contributor uses 'asyncSendToMasterAndForwardReply' method instead of 'activeMasterEndpoint.askSync' to get the status of driver. Since the driver's status is only available in active master and the 'asyncSendToMasterAndForwardReply' method iterate over all of the masters, we have to handle the response from the backup masters in the client, which the developer did not consider in the SPARK-31486 change. So drivers running in cluster mode and on a cluster with multi masters affected by this bug.
### Why are the changes needed?
We need to find if the response received from a backup master client must ignore it.
### Does this PR introduce _any_ user-facing change?
No, It's only fixed a bug and brings back the ability to deploy in cluster mode on a multi-master clusters.
### How was this patch tested?
