Hi sauravshandilya,
as I can see from your logs, there are some problems with your DB: the missing table knowagedb.QRTZ_TRIGGERS and the others table of Quartz is needed on the same schema of the Knowage tables.
Could you please check if you have executed all the DB scripts listed in the following link?
https://knowage-suite.readthedocs.io/en/7.1/installation-guide/manual-installation.html
In particular, could you check if you executed the XXX_create_quartz_schema.sql?
If you don't have that file you can download it from the download page of Knowage, at the bottom, clicking on Metadata Database Scripts, choosing the right one for your DB.
