Do the attributes of sqoop command follow some syntactical order? - hadoop

Question

For example
$ sqoop import \
--connect jdbc:mysql://localhost/userdb \
--username root \
--table emp_add \
--m 1 \ (or --num-mappers 10)
--where “city =’abcd’” \
--target-dir /whereque
is same as?
$ sqoop import \
--connect jdbc:mysql://localhost/userdb \
--username root \
--table emp_add \
--where “city =’abcd’” \
--target-dir /whereque
--m 1 \ (or --num-mappers 10)
I tried above two options and it worked. But my question is can we jumble up the attributes for all the cases?

Answer 1

Sqoop command usually follows this syntax:
sqoop command [GENERIC-ARGS] [TOOL-ARGS]
You cannot change the order of the usage. However you can change order of the tool-args.
For more have a look at documentation.

Answer 2

Actually, you don't have any generic argument in your code. Generic arguments are related to "configuration" settings. There are listed below:
-conf <configuration file> specify an application configuration file
-D <property=value> use value for given property
-fs <local|namenode:port> specify a namenode
-jt <local|jobtracker:port> specify a job tracker
-files <comma separated list of files> specify comma separated files to be copied to the map reduce cluster
-libjars <comma separated list of jars> specify comma separated jar files to include in the classpath.
-archives <comma separated list of archives> specify comma separated archives to be unarchived on the compute machines.

Answer 3

Sqoop command is shown below:
sqoop import [GENERIC-ARGS] [TOOL-ARGS]
Please see some points below on the order in which Command should be executed.
1.Generic arguments must always be placed after tool name
2.All generic arguments must always be placed before tool arguments
3.Generic arguments are always preceded by single dash(-) character.
4.Tool arguments are always preceded with 2 dashes(--), exception to which is single character arguments
