Dear Sir
I am working on pig with hadoop as a researcher. I have some problem,
following is the code and it is not able to read the input file from hdfs
in hadoop.
grunt> x_nodes = LOAD 'hdfs://localhost:50075/user/hduser/pig/planet.osm'
USING org.apache.pig.piggybank.storage.XMLLoader('node') AS
(node:chararray); grunt> p_nodes = FOREACH x_nodes GENERATE OSMNode(node)
as node; grunt> p_nodes = FILTER p_nodes BY
ST_Contains(ST_MakeBox(75.48,30.61,76.30,31.14), ST_MakePoint(node.lon,
node.lat)); grunt> STORE p_nodes INTO 'p_nodes';
HadoopVersion PigVersion UserId StartedAt FinishedAt Features 1.2.1 0.15.0
