How to customize UDF for Apache Pig? Recently, Pig needs to be used to analyze online search log data because of work requirements. I originally intended to use hive for analysis. However, for various reasons, it is useless, pig (pig0.12-cdh) has never been in touch with it, so it only takes two days to get rid of it.

recently, the scattered fairy used a few weeks of pig to deal with the analysis of our website search log data, feel very good, today wrote a note about the origin of pig, in addition to big data, probably very few people know what pig is doing, including some are programming, but not big data, Also includes some not to do programming, nor to engage in big data,

SOLR does not directly provide such a function like Java lenth, or the size of pig inside a function, then how should we query it? SOLR does not directly support such queries, but we can do this in disguise t

Introducing Apache Datafu in two parts, this article describes the part of its pig UDF. The code is open source on GitHub (except for the code.) There are also some slides introduction links).Datafu inside are some of the pig's UDFs. Functions that mainly include these aspects:Bags, Geo, hash, linkanalysis, random, sampling, sessions, sets, stats, URLsA package is appropriate for each aspect.I browsed throu
