[SPARK-15515] [SPARK-15514] [SQL] Error Handling in Running SQL Directly On
Files
#### What changes were proposed in this pull request?
This PR is to address the following issues:
- **ISSUE 1:** For ORC source format, we are reporting the strange error
message when we did not enable Hive support:
```SQL
SQL Example:
select id from `org.apache.spark.sql.hive.orc`.`file_path`
Error Message:
Table or view not found: `org.apache.spark.sql.hive.orc`.`file_path`
```
Instead, we should issue the error message like:
```
Desired Error Message:
The ORC data source must be used with Hive support enabled
```
- **ISSUE 2:** For the Avro format, we still report the error message like:
The example query is like
```SQL
SQL Example:
select id from `avro`.`file_path`
select id from `com.databricks.spark.avro`.`file_path`
Error Message:
Table or view not found: `com.databricks.spark.avro`.`file_path`
```
The desired message should be like:
```
Desired Error Message:
Failed to find data source: avro. Please use Spark package
http://sparkpackages.org/package/databricks/spark-avro";
```
- **ISSUE 3:** Unable to detect incompatibility libraries for Spark 2.0 in
Data Source Resolution.
```SQL
SQL Example:
select id from
`org.apache.spark.sql.sources.HadoopFsRelationProvider`.`file_path`
Error Message:
Table or view not found:
`org.apache.spark.sql.sources.HadoopFsRelationProvider`.`file_path`
```
The desired message should be like:
```
Desired Error Message:
org.apache.spark.sql.sources.HadoopFsRelationProvider is removed in
Spark 2.0. Please check if your library is compatible with Spark 2.0
```
