Ashish Thusoo commented on HIVE-143:
------------------------------------
A number of functions for partitions and type are no ops in the file based
metastore. Look at HiveMetaStoreClient.java, HiveMetaStore.java (RDBMS based
metastore) and MetaStoreClient.java and MetaStore.java (File based metastore)
to see the differences.
I would wait for Pete and Prasad to be back (they will be back next week)
before phasing this out.
My vote is to phase the File based one out but we should hear from those two,
specially from Pete who did the original File based metastore.
> Remove the old Metastore

> It is my understanding that there are two metastores, one HDFS based that
> isn't being used anymore and one new based on SQL databases. This causes some
> confusion and extra work for new developers, myself included. Am I correct in
> thinking that the old Metastore won't be used anymore and could be removed?
