Jakob Homan commented on GIRAPH-93:
-----------------------------------

Actually, I see what you're trying to do. You want to store the output of a Vertex job into
Hive. You can do this by writing the data to an HDFS directory that Hive is watching as a
table.  It's safe to do this with an external table, though with the new indexing features,
etc. it shouldn't be done for a managed table.  For this, you'd go directly through the metastore
API, although this is what HCatalog is also working on, so it is worth making sure we don't
duplicate work.  Also, via HCatalog we get Pig for free.
