Snappydata and external Hive compatibility
It seems that to read data from Hadoop (Hive, HDFS), we have to create exactly same external table in Snappydata. I.e having table A in Hadoop, we have to create table with same definition and EXTERNAL keyword in Snappydata to read data from Hadoop table A. This can be explained by existance of self metadata storage in Snappydata.
However, it is not clear from docs. And it's very pity that no one has answered to this question for almost two weeks.
