[SPARK-21599] Collecting column statistics for datasource tables may fail
with java.util.NoSuchElementException
## What changes were proposed in this pull request?
In case of datasource tables (when they are stored in non-hive compatible
way) , the schema information is recorded as table properties in hive
meta-store. The alterTableStats method needs to get the schema information from
table properties for data source tables before recording the column level
statistics. Currently, we don't get the correct schema information and fail
with java.util.NoSuchElement exception.
## How was this patch tested?
A new test case is added in StatisticsSuite.
