when i create a new mapreduce location in eclipse i find this error that mean the
server has newer version, than my client . how i can upgrade hadoop client
On your eclipse download the version that is on the clustwr. You are correct that it's a version mismatch, I've seen this when trying to distcp between hadoop 1 and 2. Make sure to install locally versions of client identical to cluster. Also download client configs from cluster and place them in your client directory.
more details please "install locally versions of client identical to cluster. Also download client configs from cluster and place them in your client directory."
i'm newer in hadoop world :D
If your cluster is hadoop 2.7.1 install client jars for 2.7.1 then copy core-site, hdfs-site and mapred-site.XML from cluster and put in conf directory on client. Or save yourself alot of trouble and follow this tutorial https://github.com/hortonworks-gallery/ambari-vnc-service
my cluster is hadoop 2.6.0 , client jars 2.6.0
i will read more
thank you for you help ^^
