Pre-requisites

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)

Building

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

Generating Doxygen User Docs

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

Packaging

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

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.

Running Install Check Tests

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.
