How to load data to Hive table and make it also ac

I have a table in Hive:

CREATE EXTERNAL TABLE sr2015(
creation_date STRING,
status STRING,
first_3_chars_of_postal_code STRING,
intersection_street_1 STRING,
intersection_street_2 STRING,
ward STRING,
service_request_type STRING,
division STRING,
section STRING )
ROW FORMAT SERDE 'org.apache.hadoop.hive.serde2.OpenCSVSerde' WITH SERDEPROPERTIES (
'colelction.delim'='\u0002',
'field.delim'=',',
'mapkey.delim'='\u0003',
'serialization.format'=',', 'skip.header.line.count'='1',
'quoteChar'= "\"")

The table is loaded data this way:

LOAD DATA INPATH "hdfs:///user/rxie/SR2015.csv" INTO TABLE sr2015;

Why the table is only accessible in Hive? when I attempt to access it in HUE/Impala Editor I got the following error:

AnalysisException: Could not resolve table reference: 'sr2015'

which seems saying there is no such a table, but the table does show up in the left panel.

In Impala-shell, error is different as below:

ERROR: AnalysisException: Failed to load metadata for table: 'sr2015' CAUSED BY: TableLoadingException: Failed to load metadata for table: sr2015 CAUSED BY: InvalidStorageDescriptorException: Impala does not support tables of this type. REASON: SerDe library 'org.apache.hadoop.hive.serde2.OpenCSVSerde' is not supported.

I have always been thinking Hive table and Impala table are essentially the same and difference is Impala is a more efficient query engine.

Can anyone help sort it out? Thank you very much.

Assuming that sr2015 is located in DB called db, in order to make the table visible in Impala, you need to either issue
