Hue employs some Python modules which use native code and requires certain development libraries be installed on your system. To install from the tarball, you'll need these library development packages and tools installed on your system:
# If you are using Python 3.5+, set PYTHON_VER before the build, like export PYTHON_VER=python3.8
Hue is being ran the most with MySQL InnoDB, PostgreSQL or Oracle.
The client lib MySQL-python is already included so it should work out of the box.
With the recent OSs like Ubuntu 20.04 or using Python 3, the MySQL-python lib won't compile properly and will produce an error similar to:
_mysql.c: Cannot open include file my_config.h
The lib folder needs to be swapped with https://pypi.org/project/mysqlclient/. Unfortunately for licensing reason (GPL vs Apache) this can't be officially done in the Hue repository.
Remove and add the compatible MySql lib with these two commands:
git cherry-pick 7a9100d4a7f38eaef7bd4bd7c715ac1f24a969a8 git cherry-pick e67c1105b85b815346758ef1b9cd714dd91d7ea3
Read HUE-9390 for more details.
You would need the OS
python-psycopg2 or Python psycopg2.
How to install the client lib.
Download both instantclient-basic and instantclient-sdk of the same version (126.96.36.199.0 for this example) and on your ~/.bash_profile, add
export ORACLE_HOME=/usr/local/share/oracle export VERSION=188.8.131.52.0 export ARCH=x86_64 export DYLD_LIBRARY_PATH=$ORACLE_HOME export LD_LIBRARY_PATH=$ORACLE_HOME
source ~/.bash_profile sudo mkdir -p $ORACLE_HOME sudo chmod 775 $ORACLE_HOME
then unzip the content of both downloaded zip files into the newly created $ORACLE_HOME in a way that the ‘sdk’ folder is at the same level with the other files and then
ln -s libclntsh.dylib.11.1 libclntsh.dylib ln -s libocci.dylib.11.1 libocci.dylib
cd sdk unzip ottclasses.zip
Hue comes with an older Oracle client cx_Oracle-5.2.1 Python module so it will fail. We need to do the above client install and then upgrade Hue's client module to at least cx_Oracle-5.3.
Make sure you have the
python-dev package dependencies, ensure that ORACLE_HOME and LB_LIBRARY_PATH are properly set so that pip knows which version to install, then:
echo $ORACLE_HOME $LD_LIBRARY_PATH ./build/env/bin/pip install cx_Oracle
Tip: You can also wget the proper cx_Oracle file yourself: https://pypi.python.org/pypi/cx_Oracle/.
Tip: Going to where is the Oracle client, e.g. /usr/local/share/oracle then creating a symlink similar to below could even trick the cx_Oracle-5.2.1 module to work with 12.2 without doing the pip upgrade:
ln -s libclntsh.so.12.2 libclntsh.so.11.1

Installing Python 2.7:
Check your OS Version:
Make sure “/etc/redhat-release” contains “CentOS 6.8 or 6.9” version. These instructions are tested on CentOS 6.8 and 6.9 versions only. It may or may not work on previous CentOS 6 series OS.
yum install -y centos-release-SCL yum install -y scl-utils yum install -y python27
Check your OS Version
/etc/redhat-release contains “RedHat 6.8 or 6.9” version. These instructions are tested on RedHat 6.8 and 6.9 versions only. It may or may not work on previous RedHat 6 series OS.
wget http://mirror.infra.cloudera.com/centos/6/extras/x86_64/Packages/centos-release-scl-rh-2-3.el6.centos.noarch.rpm rpm -ivh centos-release-scl-rh-2-3.el6.centos.noarch.rpm yum install -y scl-utils yum install -y python27
Check your OS Version
/etc/redhat-release contains “Oracle 6.8 or 6.9” version. These instructions are tested on Oracle 6.8 and 6.9 versions only. It may or may not work on previous Oracle 6 series OS.
wget -O /etc/yum.repos.d/public-yum-ol6.repo http://yum.oracle.com/public-yum-ol6.repo

Tip: if you run into building kerberos extension issue and see message
krb5-config: command not found, install and append it to environment variable PATH.
rpm -ql krb5-devel | grep krb5-config ## find the path of krb5-config export PATH=$PATH:/usr/lib/mit/bin
