Error to read counters into Rank operation

[John Meek <jo...@aol.com>]

Hey all,

One of my scripts is giving the below error. The script works fine when I run it in Grunt but I get the "Error to read counters into Rank operation counterSize 0". 
??
I see this  https://issues.apache.org/jira/browse/PIG-2985 but unable to decipher. Can someone let me know what this means?
