Hi,
when I do this : pig -x local
the result is :
2011-01-30 23:30:45,311 [main] INFO org.apache.pig.Main - Logging error
messages to: /home/hiba/pig_1296426645308.log
2011-01-30 23:30:46,087 [main] INFO
org.apache.pig.backend.hadoop.executionengine.HExecutionEngine - Connecting to
hadoop file system at: file:///
I can't find th error
and I like to know the steps of running a pig script:
content = load ’/home/hiba/tpch/lineitem.tbl’ using PigStorage(’|’) as
(orderkey, partkey, suppkey, linenumber, quantity:int, extendedprice:double,
discount:double, tax, returnflag, linestatus, shipdate);
filtered = filter content by PIG_PATH.CompareDate(shipdate, ’1995-01-12’,
’yyyy-MM-dd’, ’<=’);
groups = group content by (returnflag, linestatus);
records = foreach groups generate flatten(group), AVG(content.quantity),
AVG(content.extendedprice), AVG(content.discount),
COUNT(content);
--out = order records by group::returnflag, group::linestatus;
--store out into ’OUTPUT_PATH/tpch_query1’;
store records into ’OUTPUT_PATH/tpch_query1’;
and thank you
