Vihang Karajgaonkar commented on HIVE-15502:
--------------------------------------------

[~stakiar] Shouldn't these keys be present in the core-site.xml too for the Map tasks to succeed?

> Seems to only happen when trying to connect to S3 from map tasks. My {{hive-site.xml}} has the following entries:
> {code}
> <configuration>
>   <property>
>     <name>mapreduce.framework.name</name>
>     <value>local</value>
>   </property>
>   <property>
>     <name>mapred.job.tracker</name>
>     <value>local</value>
>   </property>
>   <property>
>     <name>fs.default.name</name>
>     <value>file:///</value>
>   </property>
>   <property>
>     <name>fs.s3a.access.key</name>
>     <value>[ACCESS-KEY]</value>
>   </property>
>   <property>
>     <name>fs.s3a.secret.key</name>
>     <value>[SECRET-KEY]</value>
>   </property>
> </configuration>
> {code}
> I've also noticed that now I need to copy the AWS S3 SDK jars into the lib folder before running Hive locally.
