Taras Ledkov commented on IGNITE-12903:
---------------------------------------

[~zaleslaw], there is not well implemented import from CSV at the Ignite now.
There is CSVREAD command implemented for thin JDBC but CSV parser is 
implemented invalid there.
So for the fix example i see several ways:
- waits for good implementation CSV import functionality (al least for thin 
JDBC see: IGNITE-12852);
- parse cvs files by example's code and use SQL/cache api to insert data;
- populate cache manually not from CSV.

> Fix ML + SQL examples

> are used CSVREAD function to initial load data into cluster.
> Must be changed because this function is disabled by default
