Review comment:
It may not be initialized in the constructor. It was done to avoid `null`
value in Hive storage plugin update window.
But I don't like this approach anymore.
I have described the issue here:
[DRILL-6412](https://issues.apache.org/jira/browse/DRILL-6412?focusedCommentId=16528944&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-16528944).
I think until it will be solved as mentioned in DRILL-6412, the workaround
could be used,: `"hive.metastore.schema.verification": "false"` property in
Hive `bootstrap-storage.json`. It allows instantiate Hive client properly as in
earlier 1.2 version of Drill Hive client.
Also this properties should be documented for configuring Hive Embedded
Metastore:
