--------------------------------
Summary: Unify the HiveContext
Key: SPARK-2106
URL: https://issues.apache.org/jira/browse/SPARK-2106
Project: Spark
Issue Type: Improvement
Components: SQL
Reporter: Cheng Hao
I've been working on CLI for Catalyst, and from the CLI point of view,
HiveContext may be required some changes as:
- SessionState management
`SessionState` instance creation & initialization should be done within the
wrappers, e.g. in `SharkCliDriver` or `CLIService` etc. cause they know better
how to load the use configuration and logger output redirection etc. And in
HiveContext, it can retrieve SessionState by calling `SessionState.get()`.
- HiveContext API may not be enough for CLI
Retrieving the schema from the output of `SELECT`; but `QueryExecution` is
hidden for CLI.
Get each HQL result, besides the string based result, but also we need to know
the error code, as well as the call stack if exceptions thrown.
