Sqoop cannot find mysqldump when using direct import into HDFS
The mysqldump utility is used with the "direct connector". The reason it cannot be found is that the mysqldump binary is either not on your system or not part of the PATH environment variable when Sqoop is running the MapReduce job. Things that will help: It seems like you're running...
