When you alter a Hive table by adding a new column in native environment and the table contains a special character in the column name, the mapping fails.

When you run a Hive mapping in the native environment with decimal data type in the source table having precision more than 28 and high precision mode is enabled, the mapping runs successfully but the data is not written correctly in target.

When you specify a custom JDBC driver class name, the Hive mapping fails on the Blaze and the Spark engines with an

UndeclaredThrowableException

error.
