PDL Tools is a library of reusable tools used and developed by the Pivotal Data Science and Data Engineering teams.
http://pivotalsoftware.github.io/PDLTools/
The following are the pre-requisites for building PDLTools:
Required:
- Pivotal Greenplum or Apache HAWQ (GPDB sandbox, HAWQ sandbox)
- Apache MADlib (Download)
- cmake (3.5 recommended)
- GNU C and C++ compilers (gcc, g++)
- Flex (>= 2.5.33)
- Bison (>= 2.4)
- rpmbuild
Optional:
- Doxygen (1.8.7 recommended, if generating HTML docs),
- LaTeX (if generating PDF docs)
For CentOS or Red Hat Enterprise Linux, install the pre-requisite tools:
sudo yum install cmake gcc gcc-c++ flex bison rpm-build
From either the Greenplum or HAWQ master node, follow these steps as the gpadmin user:
curl -L -o pdltools-1.7.zip https://github.com/pivotalsoftware/PDLTools/archive/v1.7.zip
unzip pdltools-1.7.zip
cd PDLTools-1.7
source /usr/local/hawq/greenplum_path.sh
mkdir build
cd build
cmake .. -DRPM_INSTALL_PREFIX=$GPHOME
curl -L -o third_party/downloads/uriparser-0.7.9.tar.bz2 https://sourceforge.net/projects/uriparser/files/uriparser-0.7.9.tar.bz2
curl -L -o third_party/downloads/cpptest-1.1.2.tar.gz https://sourceforge.net/projects/cpptest/files/cpptest-1.1.2.tar.gz
make 2> /dev/null
You can generate Doxygen docs for the project as follows:
make doc
This will create the user docs under $BUILD/doc/user/html. You can also generate a PDF of the user doc by running
cd build/doc/user/latex && make pdf
This will generate a PDF titled refman.pdf in $PDLTOOLS/build/doc/user/latex
To create an rpm package which you can ship for installation into other machines, run the following (from the build directory):
make package
When installing on a cluster, it is best to create a gppkg installer. Run the following (from the build directory):
make gppkg
Installation is a two-step process. First, you will have to install MADlib and PDL Tools on either the Greenplum or HAWQ master node. To do this, you will run the following:
gppkg -i <pdltools gppkg file>
For example, run the following (from the build directory):
gppkg -i deploy/gppkg/2.0/pdltools-1.7-hawq2.0-rhel5-x86_64.gppkg
This will place all the relevant binaries & SQL files at the appropriate location (usually $GPHOME/pdltools).
Next, you will have to install the SQL UDFs in the target database.
To install pdltools into a database of your choice, run the following (consider adding pdlpack in your PATH):
$GPHOME/pdltools/bin/pdlpack install [-s <schema name>] [-S <SUgAR schema name>] [-M <MADlib schema name>] -c <username>@<hostname>:<port>/<database name>
For example:
$GPHOME/pdltools/bin/pdlpack install -s pdltools -c gpadmin@mdw:5432/testdb
The default schemas are pdltools for the main schema, sugarlib for SUgAR and madlib to search for MADlib objects.
Post installation, you can run the unit tests in PDL Tools with the install-check command like so:
$GPHOME/pdltools/bin/pdlpack install-check -s pdltools -c gpadmin@mdw:5432/testdb
Parameters for install-check are the same as parameters for install.
If any of the tests fail, you will see an error message displayed on your console.
