https://github.com/apache/carbondata/pull/972 [CARBONDATA-1065] Added set command in carbon to update properties dynamically
**Requirement** : Currently there is no way to set the carbon properties dynamically, always need to update the carbon.properties file and restart the driver.
So it will be easy for users to give option to add/update/display/reset the properties dynamically using set and reset commands.
**Solution :**
The below sql command updates the carbon properties in driver and as well as in executor
**Add/update/display session property :**
set parameter = value --> add/update carbon session property in the corresponding session
Example : set enable.unsafe.sort = true;
set parameter --> displays given parameter value in the corresponding session
Example : set enable.unsafe.sort;
**Reset all session properties :**
Reset --> clears all session parameters in the corresponding session
Example : reset;
**SET:**
SET command displays all session supported parameters (carbon + spark) in the corresponding session
Example : SET;
**SET -V:**
set -v command displays all session parameter list along with default value and usage doc
Example : set -v;
