Harish Butani commented on HIVE-7062:
-------------------------------------

[~leftylev] documentation note:

{quote}
One of the factors checked for processing Analytic functions in Streaming mode is the 'Window
size'
For Streaming mode to kick in window size must be less than the config parameter 'hive.join.cache.size'.
Default value for this parameter is 25000.
