Hi, I am trying query a data set on HDFS using PIG.
Data = LOAD '/user/xx/20130523/*; x = FOREACH Data GENERATE cookie_id; I get below error. <line 2, column 26> Invalid field projection. Projected field [cookie_id] does not exist How do i find the column names in the bag "Data" . The developer who created the file says, it is coookie_id. Is there any way I could get schema/header for this? Thanks
