> Key: HIVE-28110
> URL: https://issues.apache.org/jira/browse/HIVE-28110
> Project: Hive
> Issue Type: Bug
> Components: Configuration
> Affects Versions: All Versions
> Environment: Ubuntu 22.04
> VSCode with Extension Pack for Java
> CommitHash: bee33d2018 on Apache Hive master branch

> Priority: Minor
> Labels: easyfix, pull-request-available
>
> When using the *getVar(Configuration conf, ConfVars var)* method of the
> MetastoreConf class, Apache breaks when e.g. trying to retrieve the
> environment variable "USE_SSL" and it isn't set in the system. The method
> then tries to cast the default value, which is the boolean false for USE_SSL,
> to a String which can't work.
>
> {quote}{{return val == null ? conf.get(var.hiveName,
> {color:#FF0000}*(String)var.defaultVal*{color}) : val;}}{quote}
>
> Also in the *getStringCollection(Configuration conf, ConfVars var)* method it
> tries to cast any default values to a String.
>
> Strangely, e.g. in the method *get(Configuration conf, String key)* the
> default value isn't casted but the .toString() method is called, which should
> be also done for the 2 methods I mentioned above.
>
> If nobody has time for that fix, I could open a PR for that.
