I am trying to load a dump created by "mysqldump -T ..." and CS is throwing error -1 during the load process. I am using the LOAD DATA INFILE command, no using cpimport directly.
MariaDB [(none)]> load data infile '/tmp/user.txt' into table quser fields terminated by "\t" enclosed by '"';
ERROR 1030 (HY000): Got error -1 "Internal error < 0 (Not system error)" from storage engine Columnstore

Looking at the logs I see:
{{2017-02-15 13:58:58 (3379) INFO : Number of rows with errors = 1. Row numbers with error reasons are listed in file /usr/local/mariadb/columnstore/bin/quser.tbl.Job_3626_3379.err

}}

However the files mentioned in the above error can not be found on the filesystem:
