Can not load files/data from a remote hadoop cluster or MongoDB database
Hi all,
here is the architechture I'm using : a local java client (pentaho) that
interacts with a remote hadoop cluster and a remote MongoDB database server.
When I try to execute a pig script (it could load data from a file under
hadoop or direclty from MongoDb server using hadoop mongoDB connector) with
my java client, each time the system responds that it can not find from
where those datas are loaded, but in the reality they absolutly exists.
here is the first pig script that loads data from an HDFS file :
*********************************************************************
weblogs = LOAD
'hdfs://sigma-server:54310/user/hduser/pdi/weblogs/parse/part/weblogs_parse.txt'
USING PigStorage('\t')
AS (
client_ip:chararray,
full_request_date:chararray,
day:int,
month:chararray,
month_num:int,
year:int,
hour:int,
minute:int,
second:int,
timezone:chararray,
http_verb:chararray,
uri:chararray,
http_status_code:chararray,
bytes_returned:chararray,
referrer:chararray,
user_agent:chararray
);
weblog_group = GROUP weblogs by (client_ip, year, month_num);
weblog_count = FOREACH weblog_group GENERATE group.client_ip, group.year,
group.month_num, COUNT_STAR(weblogs) as pageviews;
STORE weblog_count INTO
'hdfs://sigma-server:54310/user/hduser/pdi/weblogs/parse/part/mustapha-pentaho.txt';
*********************************************************************
here is the output of the Java client :
