Playing around with Hortonworks hadoop

1 min read

Going through some of the Hortonworks tutorials to see how a Hadoop environment works.


I already achieved some successes and I'm stubborn enough not to follow the tutorials to the letter. So I imported a dataset from the KNMI holding the average day temperature since 1950.


This first Pig script is to get the average temperature of Eelde according to the dataset.


Apparently the answer to this query is 8.943 degrees Celsius.


and a small adjustment to the query learns that the maximum temperature was 27.7 degrees Celsius
