Yin Huai updated SPARK-8306:
----------------------------
Description: In {{AddJar}} command, we are using
{{org.apache.hadoop.hive.ql.metadata.Hive.get().getConf().setClassLoader(newClassLoader)}}.
However, the conf returned by {{Hive.get().getConf()}} is not necessary the
one set in {{executionHive.state}}. Thus, we may fail to set the correct class
loader to {{executionHive}} in some cases. (was: We do not need to call
{{Thread.currentThread().setContextClassLoader(getClass.getClassLoader)}} to
switch classloader for executionHive since we are using the built-in hive and
the class loader returned by {{getClass.getClassLoader}} may not have user jars
in some use cases.)
> AddJar command needs to set the new class loader to the HiveConf inside
> executionHive.state.
