> Reproduced in .csv file with 25 different fields, 2712474 lines and 570 MB amount of
data.
> When I registered jar in 1st node and ran long query with function for first time I had
got error:
> {quote}
> Error: SYSTEM ERROR: SchemaChangeException: Failure while trying to materialize incoming
schema.  Errors:
>  
> Error in expression at index 0.  Error: Missing function implementation:[f(VARCHAR-OPTIONAL,
VARCHAR-OPTIONAL).  Full expression: null..
> {quote}
> When I tried to run this query second time it finished correctly. It seems another nodes
did not get new function. 
> So lazy-init does not work well on another nodes before query fails.
