> lgtm.com has identified a number of issues with the hive code base ([https://lgtm.com/projects/g/apache/hive/alerts/?mode=tree).]
This issue is to address some of the more straightforward ones. Specifically,
>  * Array index out of bounds inOpProcFactory
>  * Dereferenced variable is always null in ObjectStore
>  * Self assignment in CheckConstraint and Vectorizer
>  * several cases of Contradictory type checks
>  * several cases of Missing format argument
