>             Project: Hive
>          Issue Type: Bug
>    Affects Versions: 2.1.1
>            Reporter: Marta Kuczora

> *How to reproduce*
> - Create a partitioned table on S3:
> {noformat}
> CREATE EXTERNAL TABLE s3table(user_id string COMMENT '', event_name string COMMENT '')
PARTITIONED BY (reported_date string, product_id int) LOCATION 's3a://<bucket name>';

> {noformat}
> - Create a temp table:
> {noformat}
> create table tmp_table (id string, name string, date string, pid int) row format delimited
fields terminated by '\t' lines terminated by '\n' stored as textfile;
> {noformat}
> - Load the following rows to the tmp table:
> {noformat}
> u1	value1	2017-04-10	10000
> u2	value2	2017-04-10	10000
> u3	value3	2017-04-10	10001
> {noformat}
> - Set the following parameters:
> -- hive.exec.dynamic.partition.mode=nonstrict
> -- mapreduce.input.fileinputformat.split.maxsize=10
> -- hive.blobstore.optimizations.enabled=true
> -- hive.blobstore.use.blobstore.as.scratchdir=false
> -- hive.merge.mapfiles=true
> - Insert the rows from the temp table into the s3 table:
> {noformat}
> INSERT OVERWRITE TABLE s3table
> PARTITION (reported_date, product_id)
> SELECT
>   t.id as user_id,
>   t.name as event_name,
>   t.date as reported_date,
>   t.pid as product_id
> FROM tmp_table t;
> {noformat}
> A NPE will occur with the following stacktrace:
> {noformat}
