If the destination directory already exists in HDFS, Sqoop will refuse to import. If we use the –append argument, Sqoop will import data to a temporary directory and then rename the files into normal target directory in a manner that, it does not conflict with existing file names in that directory.
Can we append the tables data to an existing target directory?
