Large AverageThreadTokens value in impala's query profile

Hi,

 

I looked at an impala query profile and found the "AverageThreadTokens" value is super large:

 

e.g., TCounter(name:AverageThreadTokens, type:DOUBLE_VALUE, value:4607182418800017408)

 

however, on the CM impala query page, I'm seeing only a reasonable number:

 

- AverageThreadTokens: 6.35

 

Can someone please explain why the query profile has such a big number? And how could I convert that into the reasonable numbers?

 

Thanks in advance!
