[SPARK-16948][SQL] Querying empty partitioned orc tables throws excepâ¦
## What changes were proposed in this pull request?
Querying empty partitioned ORC tables from spark-sql throws exception with
`spark.sql.hive.convertMetastoreOrc=true`. This is due to the fact that the
inferschema() would end up throwing `FileNotFoundException` when no files are
present in partitioned orc tables. Patch attempts to fix it, wherein it would
fall back to metastore based schema information.
## How was this patch tested?
Included unit tests and also tested it in small scale cluster.
(If this patch involves UI changes, please attach a screenshot; otherwise,
