lirui-apache commented on issue #9450: [FLINK-13711][sql-client] Hive array values not properly displayed in… URL: https://github.com/apache/flink/pull/9450#issuecomment-521860241 > The change looks fine. However, I'm wondering if we need to convert recursively because otherwise nested non-primitive types will be still showed as non-meaningful stuff. @xuefuz `Arrays.deepToString` will take care of that for us as indicated by the JavaDoc: ``` * Returns a string representation of the "deep contents" of the specified * array. If the array contains other arrays as elements, the string * representation contains their contents and so on. This method is * designed for converting multidimensional arrays to strings. ```
