Deploy JAR for MapReduce job in Hadoop Cluster -


sorry dum question. i've 5 node hadoop cluster in centos linux.

name node / job tracker / secondary name node / data node - 2

i wrote map reduce , compiled jar. node need deploy jar?

thanks in advance.

in typical hadoop cluster , there should client node.client nodes used run client applications , cluster administration tools on hadoop cluster. client machines performing following tasks:

  1. load data in hdfs cluster
  2. submit mapreduce jobs (describing how process data)
  3. retrieve or view results of job after completion
  4. submit pig or hive queries

hadoop administrator configure client machine during installation , configuration of hadoop cluster. please identify if have client node configured in cluster. if yes, can deploy , schedule/submit job there. can use namenode deploy , submit jar using namenode deploying jar not efficient way.

if running oozie,then can put jar on hdfs , can schedule hadoop jobs through oozie.
