Installing Apache Hadoop on Mac Mavericks
In my case start-all.sh tells it is depraciated and i should use start-dfs.sh and start-yarn.sh. Both give no errors nor warnings on output (for both local and local cluster hdfs).
In Hadoop 2.4.1 jars with shared libraries are located under /libexec/share/hadoop/ and following subdirectories. To run simple MapReduce apps it is enough to add mapreduce/hadoop-mapreduce-client-core-2.4.1.jar and common/hadoop-common-2.4.1.jar.
I use the brew version, so mine is located under /usr/local/Cellar/hadoop/2.4.1/. To make it easier, I use env variable to point to the directory.


I'm not sure, but 4 GiB of ram should be enough to test the environment with some apps. It should not hang.
