Subject Re: Turn off Speculative Execution in a UDF?
Date Fri, 02 Mar 2012 23:18:27 GMT

that change I wasn't able to get a job to run with SE happening. As a
result I can't verify that the setting is doing anything. Russell, if you
can reproduce SE I'd be curious to hear if you could turn it off in
setStoreLocation.
