1."Generating splits for a textual index column allowed only in case of "-Dorg.apache.sqoop.splitter.allow_text_splitter=true" property passed as a parameter"
主要问题是“--split-by id”这个参数指定的id是一个文本格式，所以需要在命令中加入选项"-Dorg.apache.sqoop.splitter.allow_text_splitter=true"，补齐命令：
sqoop import "-Dorg.apache.sqoop.splitter.allow_text_splitter=true" \
