> 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.
