Spark SQL error: MetaException(message: Unable to fetch mwc token)

[QuinnDatatyk]

I got this issue when run spark sql query on my OneLake:

The query take too much time to response with a table just have 6 records. I checked the log, all of them were about refreshing token.

At the end, it return exception:

I checked that i  have full permissions on onelake and workspace.

Thank you for your reply @Anonymous 

I'm still stuck with this problem since last Friday. 

Sometimes the query can return results after a long run, but often it will raise a MetaException.

Hope this can be resolved soon.

I got this error today. I tried stopping and restarting my kernel and got a capacity limit exceeded exception. So this may have something to do with running actions when you have a session open but no capacity left to use.

It seems this error only occurs on Southeast Asia servers.

I tried the same case with reagion East Asia, everything is ok.

This might be an intermittent issue. Hence I request you to wait for sometime and try again. Do let me know if the issue still persists. I have informed the internal team regarding this issue.

It is difficult to tell what could be the reason for this performance. I would request you to wait for sometime and try again as it may be due to some outage issue.

Not sure why this is marked as resolved with this response?  If there is no explanation of the cause and people continue to have the issue I would not say it is resolved.  My coworker had this issue this morning in Fabric.  HiveException: MetaException(message:Unable to fetch mwc token)

I had created a support ticket for this issue. It is caused by a bug in the fabric server spark engine and affects a whole region. At that time, it was fixed after almost 2 weeks. It seems the only thing can do is to notify azure customer service and wait.
