> RebaseDateTime loadRebaseRecords should use Spark classloader instead of
> context
> --------------------------------------------------------------------------------
>
> Key: SPARK-34772
> URL: https://issues.apache.org/jira/browse/SPARK-34772
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 3.2.0, 3.1.1
> Reporter: ulysses you
> Priority: Minor
>
> With custom `spark.sql.hive.metastore.version` and
> `spark.sql.hive.metastore.jars`.
> Spark would use date formatter in `HiveShim` that convert `date` to `string`,
> if we set `spark.sql.legacy.timeParserPolicy=LEGACY` the `RebaseDateTime`
> code will be invoked. At that moment, if `RebaseDateTime` is initialized the
> first time then context class loader is `IsolatedClientLoader`. Such error
> msg would throw:
> {code:java}
> java.lang.IllegalArgumentException: argument "src" is null
