Where are hadoop jar files in hadoop 2? [closed]

Answer 1

At below location you can find folder named by distribution which you have installed , inside that there is a jar folder. /opt/cloudera/parcels/[cloudera distribution]/jars/

Example : /opt/cloudera/parcels/CDH-5.4.10/jars

Answer 2

We can get the jar files from https://mvnrepository.com website.

Example - https://mvnrepository.com/artifact/org.apache.hadoop/hadoop-core/1.2.1

Answer 3

hadoop-core-{version}.jar became hadoop-common-{version}.jar starting with Hadoop 2+

Answer 4

Actually, I faced a similar issue in the beginning. Apparently, there is no hadoop-core.jar for version 2. You'll have to download the Hadoop Common and MapReduce Client Core jars and use them both. I am sure it'll solve your problems. Hope this helps!

Edit: I just updated the links such that people can choose the appropriate version from the repository since we now come way past the initial version 2.

Answer 5

hadoop-core-${HADOOP_VERSION}.jar is in

${HADOOP_HOME}/share/hadoop/common 

directory, not ${HADOOP_HOME} directory.

Answer 6

Including JARs in folders listed below worked for me:

share\hadoop\common       
share\hadoop\common\lib   
share\hadoop\mapreduce    
share\hadoop\mapreduce\lib
share\hadoop\yarn         
share\hadoop\yarn\lib
