The HCatalogIO does not work with environments providing Hive Server 1.x which is in widespread use - as an example the latest Cloudera (5.14.2) provides 1.1.x
The HCatalogIO marks it's Hive dependencies as provided, so I believe the intention was to be open to multiple versions.
The issues come from the following:
- use of HCatUtil.getHiveMetastoreClient(hiveConf) while previous versions used the now deprecated getHiveClient(HiveConf hiveConf)
- Changes to the signature of RetryingMetaStoreClient.getProxy(...)
Given this doesn't work in a major Hadoop distro, and will not until the next CDH release later in 2018 (i.e. widespread adoption only expected in 2019) I think it would be worthwhile providing a fix/workaround.
I think building for 2.3 and relocating in your own app might be a workaround although I'm still testing it. If that is successful I'd propose adding it to the project README or in a separate markdown file linked from the README.
Does that sound like a reasonable approach please?
