set of tools__
By default, the installation path of components will follow [Filesystem
Hierarchy
Standard](https://refspecs.linuxfoundation.org/FHS_3.0/fhs/index.html), but you
can use `-PparentDir=/path` to add prefix to the path, in this example, prefix
`/path/${bigtop_version}` will be added
To avoid download wrong version of components when you have multiple
repositories configured on your machine, you can use `-PpkgSuffix` to add
bigtop version to package suffix, for example, package name `zookeeper` will be
changed to `zookeeper_3_2_0` when using `Bigtop-3.2.0`

+* __Enabling Parallel Build for packages(BIGTOP-4044)__
+
+ Apache Bigtop defaults to non-parallel builds. Use -PbuildThreads=2C to
activate Maven's parallel build feature and expedite compilation for compatible
components.
+ Append a digit and 'C' to -PbuildThreads= to set the CPU core count for
concurrent builds.
+
+ Consult the bigtop.bom file to verify component compatibility with parallel
builds; those marked with maven_parallel_build = true support this option.
