Build options:
|
||||
|
||||
* Use -Pnative to compile/bundle native code
|
||||
* Use -Dsnappy.prefix=(/usr/local) & -Dbundle.snappy=(false) to compile
|
||||
Snappy JNI bindings and to bundle Snappy SO files
|
||||
* Use -Pdocs to generate & bundle the documentation in the distribution (using -Pdist)
|
||||
* Use -Psrc to create a project source TAR.GZ
|
||||
* Use -Dtar to create a TAR with the distribution (using -Pdist)
|
||||
|
||||
Snappy build options:
|
||||
|
||||
Snappy is a compression library that can be utilized by the native code.
|
||||
It is currently an optional component, meaning that Hadoop can be built with
|
||||
or without this dependency.
|
||||
|
||||
* Use -Drequire.snappy to fail the build if libsnappy.so is not found.
|
||||
If this option is not specified and the snappy library is missing,
|
||||
we silently build a version of libhadoop.so that cannot make use of snappy.
|
||||
This option is recommended if you plan on making use of snappy and want
|
||||
to get more repeatable builds.
|
||||
|
||||
* Use -Dsnappy.prefix to specify a nonstandard location for the libsnappy
|
||||
header files and library files. You do not need this option if you have
|
||||
installed snappy using a package manager.
|
||||
* Use -Dsnappy.lib to specify a nonstandard location for the libsnappy library
|
||||
files. Similarly to snappy.prefix, you do not need this option if you have
|
||||
installed snappy using a package manager.
|
||||
* Use -Dbundle.snappy to copy the contents of the snappy.lib directory into
|
||||
the final tar file. This option requires that -Dsnappy.lib is also given,
|
||||
and it ignores the -Dsnappy.prefix option.
|
||||
|
||||
Tests options:
|
||||
|
||||
* Use -DskipTests to skip tests when running the following Maven goals:
