Fixed following Issues in Lens for Azure Migrations
# Bug in Lens-Metastore for single fact granularity --
https://issues.apache.org/jira/browse/LENS-1544. Explaination: This had a
special case for handling facts with one-update-period and
multiple-update-periods. The case which handled one-update-period had a bug
while generating the name of the hive table whole format is
update_period-fact_name, the update_period was coming as null.
# JDBCDriver.java was invoking JDBC Driver while validating the prepared
query, I don't need this functionality so blocking this via already existing
config parameter JDBC_VALIDATE_THROUGH_PREPARE.
2a) Old Flow:
esitmate()
--- | --> validate
-----| --> JDBC_VALIDATE_THROUGH_PREPARE condition to prepare through if
condition
-----|--> prepareInternal()
----------------|--> rewrite -- Rewritting take place
2b) New Flow:
