database - Cassandra: copy null -


i have problem copy command in cassandra. try move old database on new server when use copy receives error:

failed import 1 rows: parseerror - invalid literal int() base 10: 'null',  given without retries

some fields null , need keep informations. csv created copy to:

copy tabel './db.csv' null='null'

if try make csv without null='null' receives error:

failed import 1 rows: parseerror - invalid literal int() base 10: '',  given without retries

how can assign null int ? cassandra version: [cqlsh 5.0.1 | cassandra 2.2.6 | cql spec 3.3.1 | native protocol v4]

i have found bug description in jira:

https://issues.apache.org/jira/browse/cassandra-11549

and patch worked me both on linux , windows. have manually replaced 1 line of code in given file:

https://github.com/stef1927/cassandra/commit/6e7664380bb6ddea37efd5f866b7631fdc84bdac

does work well?

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
