> When multiple queries are run in LLAP, stripe metadata cache misses were observed even
though enough memory was available. 
> https://github.com/apache/hive/blob/master/llap-server/src/java/org/apache/hadoop/hive/llap/io/encoded/OrcEncodedDataReader.java#L655.
Even in cases when data was found in cache, it wasn't getting used as {{globalnc}} changed
from query to query.  Creating a superset of existing indexes with {{globalInc}} would be
helpful. 
> This would be lot more beneficial in cloud storage where opening and reading small of
data can be expensive compared to HDFS.
