WSO2 BAM文档

Question

I am trying to set up WSO2 BAM and API Manager integration by following the documentation at Publishing API Runtime Statistics .

There is a line in the documentation to drop Hive table

add the following line at the beginning of the Hive script and rerun. drop table ;

It is not clear where to add this line and what exact table to drop. Can someone provide more information on this one?

BAM is throwing following exception and I am assuming it is related to above changes required

Answer 1

Log into BAM. Select Main -> Analytics -> Add. This will bring up an editor to provide your script. You can give drop table statements here and then click execute. You don't need to save this before hitting execute.
