10/19/16 - Installation of MADlib on GPDB 4.3.10

This is an important note for installation of MADlib on GPDB 4.3.10.  It does not apply to any other releases.

1) Fix madpack install utility
* issue: After gppkg installation MADlib, you must run the script 
fix_madpack.sh BEFORE running the madpack utility (see below)

2) install checks
* issue: some failures may happen on MADlib install checks,  however the MADlib install actually completed OK.

This is a poor customer experience that will be fixed in the next release. On the positive side, once the installation is done, MADlib should work OK.

------------------------------

More on fixing madpack from #1 above:

After gppkg installation MADlib, you must run the script 
fix_madpack.sh BEFORE running the madpack utility.
The syntax for fix_madpack.sh is below.

This can be somewhat confusing because after gppkg
installation, you will get a message on the console
that says:

“Please run the following command to deploy MADlib
usage: madpack install [-s schema_name] -p hawq -c user@host:port/database
etc...”

So the correct order of operations is:

1. gppkg install of MADlib
2. run fix_madpack.sh
3. run madpack utility

10/7/16 - Installation of MADlib on HDB/HAWQ 2.0.1

This is an important note for installation of MADlib on
HDB/HAWQ 2.0.1.

1) gppkg
* issue: does not end cleanly after installing MADlib so you need to manually exit via ctl-z, however the MADlib install actually completed OK.

2) QuickLZ compression
* issue: After gppkg installation MADlib, you must run the script 
remove_compression.sh BEFORE running the madpack utility (see below)

3) install checks
* issue: some failures may happen on MADlib install checks,  however the MADlib install actually completed OK.

This is a poor customer experience that will be fixed in the next release. On the positive side, once the installation is done, MADlib should work OK.
