Install Python 3.6.x from https://www.python.org/downloads/ or via homebrew
Check that python3 has been installed by running it at the terminal:

$ python3
>>> Python 3.6.4

Download get-pip.py from https://bootstrap.pypa.io/get-pip.py and install (this should already be installed if python was installed from python.org or homebrew):

$ curl -O https://bootstrap.pypa.io/get-pip.py
$ sudo python3 get-pip.py

For /var/log/system.log full of errors like these ones:

kernel[0]: Sandbox: com.apple.Addres(XXXXX) deny(1) network-outbound /private/var/run/mDNSResponder
com.apple.AddressBook.InternetAccountsBridge[XXXXX]: dnssd_clientstub ConnectToServer: connect()-> No of tries: 1
com.apple.AddressBook.InternetAccountsBridge[XXXXX]: dnssd_clientstub ConnectToServer: connect() failed path:/var/run/mDNSResponder Socket:4 Err:-1 Errno:1 Operation not permitted

How to fix it?

I was chasing down another issue (slow "Save As") and thought these two issues may have been related (with QuickLook being the common broken link). Unfortunately, my "Save As" dialog is still miserably slow on the initial load; but IconServicesAgent hasn't gone above 30MB and he rarely makes an appearance in the Console!

Some of these steps may not be necessary, but here are all of the steps I took that inadverdently put IconServicesAgent back in its place. Note: all commands are a single-line, if they appear to be multiple that's just the forum formatting.

Check for any QuickLooks related .plist files. In a terminal: mdfind com.apple.quicklook. -name .plist
I only had files at the system level (specifically within /System/Library/LaunchAgents/). If you have others, modify the directions below to take that into account (re-introducing plist files from the system level back up to the user).
Make some temporary directories to store these plist files, just in case: mkdir ~/tmp-quicklook

Step 1 (Creating a bootable macOS Sierra ISO for VirtualBox):

hdiutil attach /Applications/Install\ macOS\ Sierra\ Public\ Beta.app/Contents/SharedSupport/InstallESD.dmg -noverify -nobrowse -mountpoint /Volumes/install_app
hdiutil create -o /tmp/Sierra.cdr -size 7316m -layout SPUD -fs HFS+J
hdiutil attach /tmp/Sierra.cdr.dmg -noverify -nobrowse -mountpoint /Volumes/install_build
asr restore -source /Volumes/install_app/BaseSystem.dmg -target /Volumes/install_build -noprompt -noverify -erase
rm /Volumes/OS\ X\ Base\ System/System/Installation/Packages

Configure S3 filesystem support for Spark on OSX

Homebrew installed Spark 1.6.x

Install hadoop to get the required jars (brew install hadoop)
Create a spark-env.sh (cp /usr/local/Cellar/apache-spark/1.6.1/libexec/conf/spark-env.sh.template /usr/local/Cellar/apache-spark/1.6.1/libexec/conf/spark-env.sh)
Set HADOOP_CONF_DIR in spark-env.sh (export HADOOP_CONF_DIR=/usr/local/Cellar/hadoop/2.7.2/libexec/etc/hadoop/)
Add the required jars to the SPARK_CLASSPATH in spark-env.sh
