> Key: HIVE-22154
> URL: https://issues.apache.org/jira/browse/HIVE-22154
> Project: Hive
> Issue Type: Bug
> Components: Hive, HiveServer2, llap
> Affects Versions: 3.1.0, 3.1.1
> Reporter: Harsh Takkar
> Priority: Critical
>
> As a user if we add multiple filters with "or" operator on spark dataframe it
> should be enclosed properly with correct brackets but in the current version
> of hwc multiple filters are not enclosed with proper brackets
> for e.g.
> df = df.fiter("condition1 or condition2")
> df = df.filter("condition3 and condition4")
> the resultant query created is as follows
> *(condition1) or (condition2) and (condition3) and (condition4)*
> ideally it should be as follows
> *((condition1) or (condition2)) and ((condition3) and (condition4))*
