Re: Data sample error

Which CDH version? Are you using CM?

Did you find a solution for this?

Re: Data sample error

It might have been an issue in this CDH version, but should be fixed in
latest 5.5.x or 5.

Impala was not configured to allow Hue to refetch data:
"Restarting of fetch requires enabling of query result caching"

e.g. it works on http://demo.gethue.com/impala which is 5.5

Hi,

 

We already have a 5.5 Cloudera Version and it isn't working right now. We plan to migrate to 5.5.2 asap, I don't know if there the problem is solved.

 

I will give some feedback about this

 

 

Thank you.

Re: Data sample error

In the Impala configuration, is this set?

Result Cache Maximum Size
max_result_cache_size

100000
