猪HBASE失败; 储存CSV

Question

I'm beginning with the environment Hadoop, HBase, Pig; I would storer a database on a Hbase table; here are my requeste:

hbase-> create to create my database.

I rebooted my CVS file on HDFS file hadoop dfs-copyFromLocal ~ /data.csv / user / hduser / location.csv

I executed my requeste PIG

raw_data = LOAD '/ user / hduser / data.csv' USING PigStorage (';') AS ( WMO: int, maturity: charArray, temperature: int, temps_present: int, direction_du_vent: int, force_du_vent: int, pressure: int);

STORE INTO raw_data 'hbase :/ / TrafficFlowGrenoble' USING org.apache.pig.backend.hadoop.hbase.HBaseStorage ( WMO: int maturity: charArray temperature: int temps_present: direction_du_vent int int force_du_vent int pressure: int ');

HERE IS MY ERRORS: 2013-07-22 22:30:31,870 [main] ERROR org.apache.pig.tools.pigstats.PigStatsUtil - 1 map REDUCE job (s) failed! 2013-07-22 22:30:31,872 [main] INFO org.apache.pig.tools.pigstats.SimplePigStats - Script Statistics:

如果上面的代码与您输入的文件完全一样，那么输入的文件是“ / user / hduser / location .csv”而不是data.csv，因此Pig找不到它
