ExecPlanRequest rpc exception error while COMPUTE STATS

avatar
Rising Star

Hello,

 

Today, when I run "compute stats" command in Impala, I got this kind of error.

Can you tell me what I need to check to root-cause the issue?

 

I've restart Impala cluster in case, but still doesn't work.

 

Thank you

I found out what caused this issue in this case.

 

Nodes have different Impala version, such as 2.8, 2.4 etc.

The interesting thing is that `compute stats` operation didn't work if run in Impala 2.8,

but the operation works in Impala 2.4.

 

Anyway, I hope this can help you solve your problem.

 

Thank you

Is this related to kerberos authentication??
