I did. I inserted my own records into the repo_version, cluster_version, and 
host_version tables manually, and no sequences existed for the last 2 tables.
Just to be safe, I added code to get the number of rows to first insert the 
sequence if not already present.

Will fix.

We do not support this for HDP 2.0 since it does not have any upgrade packs.

That's a good point. I can either
1) insert the sequence as 0 if no records are present, which is very likely to 
be the case.
2) write a named query to get the max(ID) in each one of these tables (more 
robust, but I don't really expect anyone on HDP 2.1 to have any records in 
those tables).
