Hadoop java.lang.RuntimeException: java.lang.NoSuchMethodException
I posted the details here but I am not sure what's causing this exception in the map-phase. Does anything look wrong with my class implementation that hadoop is unable to recognize? https://stackoverflow.com/questions/54135130/hadoop-java-lang-runtimeexception-java-lang-nosuchmethodexception
Contributing to open source
Hello, Just wanted to get some suggestions on which hadoop ecosystem projects could i take a look at to begin contributing to open source. Any upcoming and interesting projects those are gaining momentum and a beginner like me can help out with? Any advice or guidance will be of much help. Kind regards Snehil
Re: Contributing to open source
Hello, I don't use those at work, but am highly interested in getting involved, so am looking at open source projects. I will take a look at the link. thanks for your advice.

Re: Any working VM of Apache Hadoop ?
Hey Krish, I just downloaded Hortonworks Sandbox and HDP2.2 ( http://hortonworks.com/blog/announcing-hdp-2-2/) has an impressive stack built in and ready to go out of the box making things simple for newbies.. you might want to try that http://hortonworks.com/products/hortonworks-sandbox/ Kind regards, Snehil Wakchaure Software Engineer Cerner Corporation On Sun, Jan 18, 2015 at 11:22 AM, Olivier Renault orena...@hortonworks.com wrote: You should be able to also download one from every Hadoop vendors. - Hortonworks - http://hortonworks.com/products/hortonworks-sandbox/ - Cloudera - ...

Re: The future of MapReduce

Hadoop v1=HDFS+MapReduce Hadoop v2=HDFS+YARN (+ MapReduce part of the core, but now considered optional to get work done) v2 adds a better resourcing framework. Now you can run Storm, Spark, MapReduce, etc. on Hadoop and mix-and-match jobs/tasks with whatever your requirements, which may actually be both batch stuff and/or real-time. Not sure if that clarifies things... Just like you can evaluate all kinds of Apache ecosystems products to meet your needs, MapReduce is no longer the only kid on the bock.

Is Storm the future or are both technologies necessary? B.
