I am new to Julia language and found it very interesting. As it says it is hadoop ready I wanted to test this using my local hadoop cluster. I installed latest version of julia in my debian 32 bit machine and wrote few simple scripts, sort of Hello world stuffs. Now, I have pulled HDFS and YARN interface package from the below site
https://github.com/JuliaParallel/HDFS.jl
https://github.com/JuliaParallel/Elly.jl
Do not know How to install these in my machine and use these package for querying HDFS cluster and run few map-reduce tasks.
Any pointers will be very much helpful here.
Thanks in advance
Thanks Gnimuc Key, I took a nightly build version (0.4) and I could install Elly package

I installed pyspark 2.2.0 with pip, but I don't see a file named spark-env.sh nor the conf directory. I would like to define variables like SPARK_WORKER_CORES in this file. How should I proceed?
I am using Mac OSX El Capitan, python 2.7.
PySpark from PyPi (i.e. installed with pip or conda) does not contain the full PySpark functionality; it is only intended for use with a Spark installation in an already existing cluster, in which case you might want to avoid downloading the whole Spark distribution. From the docs:
The Python packaging for Spark is not intended to replace all of the
other use cases. This Python packaged version of Spark is suitable for
interacting with an existing cluster (be it Spark standalone, YARN, or
Mesos) - but does not contain the tools required to setup your own
standalone Spark cluster. You can download the full version of Spark
from the Apache Spark downloads page.
So, what you should do is download Spark as said above (PySpark is an essential component of it).
I have installed hadoop. I used hadoop-2.7.0-src.tar.gz and hadoop-2.7.0.tar.gz files. And uses apache-maven-3.1.1 to collect the hadoop tar file for windows.
After so many tries I made it run. It was difficult to install hadoop without knowing what I am doing.
Now I want to install Hive. Do I have to collect Hive files with Maven?
If yes what folders should I use to collect them?
And then I want to install sqoop.
Any information is appreciated.
I have not tried on windows but I did on Linux - Ubuntu, and I have detailed these step by step in my blog over here - Hive Install
Have a look, I think most of the steps will be necessary in the same sequence as described but nature of command may be different for windows.
I'm running debian. I'm new to Hadoop. Sometime back, I was trying to install Hadoop. I'm not sure if I've successfully installed. When I enter command at terminal
hadoop version
I see the output:
Hadoop 2.7.1
Subversion https://git-wip-us.apache.org/repos/asf/hadoop.git -r 15ecc87ccf4a0228f35af08fc56de536e6ce657a
Compiled by jenkins on 2015-06-29T06:04Z
Compiled with protoc 2.5.0
From source with checksum fc0a1a23fc1868e4d5ee7fa2b28a58a
This command was run using /home/xxxxxxx/java/hadoop-2.7.1/share/hadoop/common/hadoop-common-2.7.1.jar
Is hadoop installed properly? If not, what other tests I've to do? If yes, is there some simple "get-started" tutorial/exercise you're aware of, that can help me get started with?
Thank you!
I want to install Cloudera distribution of Hadoop and Spark using tarball.
I have already set up Hadoop in Pseudo-Distributed mode in my local machine and successfully ran a Yarn example.
I have downloaded latest tarballs CDH 5.3.x from here
But the folder structure of Spark downloaded from Cloudera is differrent from Apache website. This may be because Cloudera provides it's own version maintained separately.
So, as there are no documentation I have found yet to install Spark from this Cloudera's tarball separately.
Could someone help me to understand how to do it?
Spark could be extracted to any directory. You just need to run the ./bin/spark-submit command (available in extracted spark directory) with required parameters to submit the job. To start spark interactive shell, please use command ./bin/spark-shell.
Hi i am new to Big Data concept. I have installed Hbase0.98-hadoop2. Does it mean that hadoop 2 has also been installed on my machine along with HBase? If yes then how can I run hadoop?
I have no idea about Ubuntu packages. After the installation, you can do one quick experiment. In the shell, just type (incomplete command):
$ hadoop
If it tells you command not found: hadoop, then no, you don't have Hadoop installed.
Follow the link for hadoop installation -
