Hadoop Jar Files

[Praveen Sripati <pr...@gmail.com>]

Hi,

I have extracted the hadoop-0.20.2, hadoop-0.20.203.0 and hadoop-0.21.0
files.

In the hadoop-0.21.0 folder the hadoop-hdfs-0.21.0.jar,
hadoop-mapred-0.21.0.jar and the hadoop-common-0.21.0.jar files are there.
But in the  hadoop-0.20.2 and the hadoop-0.20.203.0 releases the same files
are missing.

Have the jar files been packaged differently in the 0.20.2 and 0.20.203.0
releases or should I get these jars from some other projects?

Thanks,
Praveen

Praveen,

Yes, in 0.21.x series, the jars are broken down by the project they
belong to (Common, HDFS, and MapReduce). This was due to splitting of
the Hadoop projects into subcomponents.

In 0.20.x it would be one single jar containing class files of all the
three projects (hadoop-core jar).
