Hadoop Pig Programming Examples Flight Data

Finding how many flights between origin and destination by using Hadoop pig Programming,            In our input data we have some fields like 

origin destination origincity destncity passengers seats flights distance date population now our work is Finding how many flights between origin and destination please find the below link for input data .

Input Data -------> airlineinformation (1)

We can execute the pig programming script in two ways 
i)  Local Mode Execution 
ii) HDFS/Server Mode Execution 

In Local Mode Execution the input data as taken from the local and generate the output on top of       local but in HDFS/Server Mode Execution the input data should be taken from HDFS and output also generates on top of HDFS . 
In real time cases we should use HDFS/Server mode Execution .

Hadoop Pig Programming Examples on Flight Travailing Data

Local Mode Execution In Hadoop Pig Programming


In above Hadoop Pig Programming script we execute the script in Local mode that means variable A   is LOADING the input data from local system not from HDFS and output also stored on top of local system not on top of HDFS.

HDFS/Server Mode Execution In Hadoop Pig Programming

In above Hadoop Pig Programming script we execute the script in HDFS/Server mode that means      variable A is LOADING the input data from HDFS not from Local and output also stored on top of      HDFS not on top of Local.
