Apache Spark reassigned SPARK-16222:
------------------------------------
Assignee: (was: Apache Spark)
> JDBC Sources: Handling illegal input values for `fetchsize` and `batchsize`
> ---------------------------------------------------------------------------
>
> Key: SPARK-16222
> URL: https://issues.apache.org/jira/browse/SPARK-16222
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.0.0
> Reporter: Xiao Li
>
> For JDBC data sources, users can specify `batchsize` for multi-row inserts
> and `fetchsize` for multi-row fetch. A few issues exist:
> - The property keys are case sensitive. Thus, the existing test cases for
> `fetchsize` use incorrect names. Basically, the test cases are broken.
> - No test cases exist for `batchsize`.
> - We do not detect the illegal input values for `fetchsize` and `batchsize`.
> For example, when `batchsize` is zero, we got the following exception:
> ```
> Job aborted due to stage failure: Task 0 in stage 0.0 failed 1 times, most
> recent failure: Lost task 0.0 in stage 0.0 (TID 0, localhost):
> java.lang.ArithmeticException: / by zero
> ```
> when `fetchsize` is less than zero, we got the exception from the underlying
> JDBC driver:
> ```
> Job aborted due to stage failure: Task 0 in stage 0.0 failed 1 times, most
> recent failure: Lost task 0.0 in stage 0.0 (TID 0, localhost):
> org.h2.jdbc.JdbcSQLException: Invalid value "-1" for parameter "rows"
> [90008-183]
> ```
