Multiple python versions on Mac

 I had MacOS Mojave.  It needed multiple versions of pythons esp. I needed a version of Python between 2.6.x and 3.0.x.  I came across this nice article 

https://medium.com/faun/pyenv-multi-version-python-development-on-mac-578736fb91aa

I followed all steps but when I tried to install 2.7.0 and 2.7.1 I ran into this issue.

ERROR: The Python ssl extension was not compiled. Missing the OpenSSL lib?

I had openssl installed but it seems it was not the version it was looking for. Eventually I was able to install python version 2.7.15. Looks like 2.7.15 was using the openssl lib which I had it installed hence no issues. 

bash-3.2$ pyenv install 2.7.15

python-build: use openssl@1.1 from homebrew

python-build: use readline from homebrew

DBeaver

Recently I used this tool for connecting to Hive via Knox gateway.  Good thing about this tool is that it automatically downloads the driver and configures it. That  is a pain in tools like Squirrel.  It also makes a JDBC connection to Hive.  Below is how the HOST and JDBC URL settings look like : HOST : <KNOX_HOST>:8443/;ssl=true;transportMode=http;httpPath=gateway/<topology>/hive JDBC URL :  jdbc:hive2://<KNOX_HOST>:8443/;ssl=true;transportMode=http;httpPath=gateway/<topology>/hive What I noticed on my setup was that if you keep the default port which 10000 and you set it to 8443 , it does not work. So you have to keep it blank.  That may be specific to my setup. Also you might notice that ssl=true but there are  no  sslTrustStore= < Path to the “.jks” file in the NiFi node > ;trustStorePassword= < TrustStore Password>  parameters. The reason is if you import the gateway cert  into the trus...
