I use ImpalaJDBC41 to make inserts on kudu tables. The problem is when string contains "+", then inserted string is suffixed by space char. For example value is "ABC+", then column value is "ABC+ ".
Insert is made by org.springframework.jdbc.core.simple.SimpleJdbcInsert
Column type is STRING
Dependencies:
Kudu: 1.5.0-cdh5.13.0
Spring Boot: 2.0.5.RELEASE
ImpalaJDBC41: 2.6.3
Problem solved. Upgrade ImpalaJDBC41 to 2.6.15.1017 helped
