YongHun Jeon updated HADOOP-10721:
----------------------------------
Priority: Major (was: Critical)
> The result does not show up after running hive query on Swift.
> --------------------------------------------------------------
>
> Key: HADOOP-10721
> URL: https://issues.apache.org/jira/browse/HADOOP-10721
> Project: Hadoop Common
> Issue Type: Bug
> Components: fs/swift
> Reporter: YongHun Jeon
>
> I configured Hadoop and Swift system as the site is mentioned : http://docs.openstack.org/developer/sahara/userdoc/hadoop-swift.html.
> So, I succeeded to access the Swift from Hadoop.
> I am running TPC-H performance test on Hadoop system integrated with Swift.
> I ran the below hive query.
> ---------------------------------------------------------------------------------------------
> DROP TABLE lineitem;
> DROP TABLE q1_pricing_summary_report;
> -- create tables and load data
> Create external table lineitem (L_ORDERKEY INT, L_PARTKEY INT, L_SUPPKEY INT, L_LINENUMBER INT, L_QUANTITY DOUBLE, L_EXTENDEDPRICE DOUBLE, L_DISCOUNT DOUBLE, L_TAX DOUBLE, L_RETURNFLAG STRING, L_LINESTATUS STRING, L_SHIPDATE STRING, L_COMMITDATE STRING, L_RECEIPTDATE STRING, L_SHIPINSTRUCT STRING, L_SHIPMODE STRING, L_COMMENT STRING) ROW FORMAT DELIMITED FIELDS TERMINATED BY '|' STORED AS TEXTFILE LOCATION 'swift://test.provider/tpch/lineitem';
> -- create the target table
> CREATE external TABLE q1_pricing_summary_report ( L_RETURNFLAG STRING, L_LINESTATUS STRING, SUM_QTY DOUBLE, SUM_BASE_PRICE DOUBLE, SUM_DISC_PRICE DOUBLE, SUM_CHARGE DOUBLE, AVE_QTY DOUBLE, AVE_PRICE DOUBLE, AVE_DISC DOUBLE, COUNT_ORDER INT) LOCATION 'swift://test.provider/user/result/q1_pricing_summary_report';
> set mapred.min.split.size=536870912;
> -- the query
> INSERT OVERWRITE TABLE q1_pricing_summary_report
> SELECT
> L_RETURNFLAG, L_LINESTATUS, SUM(L_QUANTITY), SUM(L_EXTENDEDPRICE), SUM(L_EXTENDEDPRICE*(1-L_DISCOUNT)), SUM(L_EXTENDEDPRICE*(1-L_DISCOUNT)*(1+L_TAX)), AVG(L_QUANTITY), AVG(L_EXTENDEDPRICE), AVG(L_DISCOUNT), COUNT(1)
> FROM
> lineitem
> WHERE
> L_SHIPDATE<='1998-09-02'
> GROUP BY L_RETURNFLAG, L_LINESTATUS
> ORDER BY L_RETURNFLAG, L_LINESTATUS;
> ---------------------------------------------------------------------------------------------
> You can get the files(such as lineitem) for the test through running dbgen which is in this site : http://www.tpc.org/tpch/.
> I saw the some temporary files are generated and deleted. However, the result does not show up after running hive query.
