File size in the /resultset api response
Hey All,
In case of persistent resultset,
*/queryapi/queries/{queryHandle}/resultset* response contains the resultset
HDFS path and the number of rows in the resultset.
I was wondering if we could also include the size of hdfs resultset
file in the response. The information on the size of the file can be
obtained using WebHDFS APIs. I think this information could be useful for
the user. What do you guys think ?
Regards,
Deepak Kumar Barr

Jaideep,
I just looked at FileSystem APIs and I found that
FileSystem.getFileStatus().getLen() will give us the file size. This is
definitely a better option than webHDFS APIs. I will go ahead and create a
JIRA for this.

Hi Deepak,
File size is certainly useful for persistent result sets, but do we need
WebHdfs for it? Its an extra server to run, can we get it from the
FileSystem API itself?
Thanks,
Jaideep
