> We have a use case where we have a list of partitions that are created as a result of a batch job (new or updated) outside of Hive and would like to synchronize them with the Hive MetaStore. We would like to use the HCatalog {{HCatClient}} but it currently does not seem to support this. However it is possible with the {{HiveMetaStoreClient}} directly. I am proposing to add the following method to {{HCatClient}} and {{HCatClientHMSImpl}}:
> A method for altering partitions. The implementation would delegate to {{HiveMetaStoreClient#alter_partitions}}. I've used "update" instead of "alter" in the name so it's consistent with the {{HCatClient#updateTableSchema}} method.
> {code}
> public void updatePartitions(List<HCatPartition> partitions) throws HCatException
> {code}
