Change subject: IMPALA-14405 ADDENDUM: Catch exception for bad column names ...................................................................... IMPALA-14405 ADDENDUM: Catch exception for bad column names This commit is a fix on top of IMPALA-14405 for the Calcite planner. The original commit matches column names from the expression in the select clause. For instance, if the query is "select 1 + 1", the label in impala-shell will be "1 + 1". It accomplished this by retrieving the string from the SqlNode object through the MySql dialect. However, when the expression doesn't succeed in the MySql dialect, an AssertionError gets thrown, causing the query to fail. We don't want the query to fail, we just want to go back to using the Calcite expression, e.g. EXPR$0. This occurred with this specific query: "select timestamp_col + interval 3 nanoseconds" So now the exception is caught and the default label name is used. Eventually we should try to match what Impala has, but this is a harder problem to fix.
