+sqoop-import-all-tables+
|
|
-------------------------
|
|
|
|
Purpose

~~~~~~~

include::import-all-tables-purpose.txt[]

|
|
|
Syntax
|
|
~~~~~~
|
|
|
|
----
|
|
$ sqoop import-all-tables (generic-args) (import-args)
|
|
$ sqoop-import-all-tables (generic-args) (import-args)
|
|
----
|
|
|
|
Although the Hadoop generic arguments must preceed any import arguments,
|
|
the import arguments can be entered in any order with respect to one
|
|
another.
|
|
|
|
include::common-args.txt[]
|
|
|
|
.Import control arguments:
|
|
[grid="all"]
|
|
`----------------------------`---------------------------------------
|
|
Argument Description
|
|
---------------------------------------------------------------------
|
|
+\--as-sequencefile+ Imports data to SequenceFiles
|
|
+\--as-textfile+ Imports data as plain text (default)
|
|
+\--direct+ Use direct import fast path
|
|
+\--direct-split-size <n>+ Split the input stream every 'n' bytes when\
|
|
importing in direct mode
|
|
+\--inline-lob-limit <n>+ Set the maximum size for an inline LOB
|
|
+-m,\--num-mappers <n>+ Use 'n' map tasks to import in parallel
|
|
+\--warehouse-dir <dir>+ HDFS parent for table destination
|
|
+-z,\--compress+ Enable compression
|
|
---------------------------------------------------------------------
|
|
|
|
These arguments behave in the same manner as they do when used for the
|
|
+sqoop-import+ tool, but the +\--table+, +\--split-by+, +\--columns+,
|
|
and +\--where+ arguments are invalid for +sqoop-import-all-tables+.

.Code generation arguments:
|
|
[grid="all"]
|
|
`------------------------`-----------------------------------------------
|
|
Argument Description
|
|
-------------------------------------------------------------------------
|
|
+\--bindir <dir>+ Output directory for compiled objects
|
|
+\--jar-file <file>+ Disable code generation; use specified jar
|
|
+\--outdir <dir>+ Output directory for generated code
|
|
+\--package-name <name>+ Put auto-generated classes in this package
|
|
-------------------------------------------------------------------------
|
|
|
|
The +import-all-tables+ tool does not support the +\--class-name+ argument.
|
|
You may, however, specify a package with +\--package-name+ in which all
|
|
generated classes will be placed.
