 URL: https://issues.apache.org/jira/browse/HADOOP-9211
 Project: Hadoop Common
  Issue Type: Bug
  Components: conf
Affects Versions: 2.0.2-alpha
Reporter: Sarah Weissman


hadoop-env.sh as included in the 2.0.2alpha release tarball contains:
export HADOOP_CLIENT_OPTS="-Xmx128m $HADOOP_CLIENT_OPTS"

This overrides any heap settings in HADOOP_HEAPSIZE.

The http://hadoop.apache.org/releases.html page links to 
http://www.apache.org/dyn/closer.cgi/hadoop/common/ which provides a list of 
mirrors.  The first one on the list (for me) is 
http://www.alliedquotes.com/mirrors/apache/hadoop/common/ which is 404.

I checked the rest of the mirrors in the list and only alliedquotes is 404.

 Summary: Add shell command to dump file checksums
 Key: HADOOP-9209
 URL: https://issues.apache.org/jira/browse/HADOOP-9209
 Project: Hadoop Common
  Issue Type: Bug
  Components: fs, tools
Affects Versions: 3.0.0, 2.0.3-alpha
Reporter: Todd Lipcon
Assignee: Todd Lipcon


Occasionally while working with tools like distcp, or debugging certain issues, 
it's useful to be able to quickly see the checksum of a file. We currently have 
the APIs to efficiently calculate a checksum, but we don't expose it to users. 
This JIRA is to add a "fs -checksum" command which dumps the checksum 
information for the specified file(s).

Re: python streaming error

2013-01-14 Thread Andy Isaacson 
Hadoop Streaming does not magically teach Python open() how to read
from "hdfs://" URLs. You'll need to use a library or fork a "hdfs dfs
-cat" to read the file for you.

[jira] [Created] (HADOOP-9207) version info source checksum does not include all source files

 Summary: version info source checksum does not include all source 
files
 Key: HADOOP-9207
 URL: https://issues.apache.org/jira/browse/HADOOP-9207
 Project: Hadoop Common
  Issue Type: Bug
  Components: build
Affects Versions: 3.0.0
Reporter: Chris Nauroth


The build process takes an MD5 checksum of the source files in Common and YARN. 
 The HDFS version info command prints the checksum from Common.  The YARN 
version info command prints the checksum from YARN.  This is incomplete in that 
the HDFS source code is never included in the checksum, and 2 different YARN 
builds with the same YARN code but different Common code would have the same 
checksum.

[jira] [Created] (HADOOP-9206) "Setting up a Single Node Cluster" instructions need improvement in 0.23.5/2.0.2-alpha branches

 Summary: "Setting up a Single Node Cluster" instructions need 
improvement in 0.23.5/2.0.2-alpha branches
 Key: HADOOP-9206
 URL: https://issues.apache.org/jira/browse/HADOOP-9206
 Project: Hadoop Common
  Issue Type: Bug
  Components: documentation
Affects Versions: 0.23.5, 2.0.2-alpha
Reporter: Glen Mazza


Hi, in contrast to the easy-to-follow 1.0.4 instructions 
(http://hadoop.apache.org/docs/r1.0.4/single_node_setup.html) the 0.23.5 and 
2.0.2-alpha instructions 
(http://hadoop.apache.org/docs/r2.0.2-alpha/hadoop-yarn/hadoop-yarn-site/SingleCluster.html)
 need more clarification -- it seems to be written for people who already know 
and understand hadoop.  In particular, these points need clarification:

1.) Text: "You should be able to obtain the MapReduce tarball from the release."

Question: What is the MapReduce tarball?  What is its name?  I don't see such 
an object within the hadoop-0.23.5.tar.gz download.

2.) Quote: "NOTE: You will need protoc installed of version 2.4.1 or greater."

Protoc doesn't have a website you can link to (it's just mentioned offhand when 
you Google it) -- is it really the case today that Hadoop has a dependency on 
such a minor project?  At any rate, if you can have a link of where one goes to 
get/install Protoc that would be good.

3.) Quote: "Assuming you have installed hadoop-common/hadoop-hdfs and exported 
$HADOOP_COMMON_HOME/$HADOOP_HDFS_HOME, untar hadoop mapreduce tarball and set 
environment variable $HADOOP_MAPRED_HOME to the untarred directory."

I'm not sure what you mean by the forward slashes: hadoop-common/hadoop-hdfs 
and $HADOOP_COMMON_HOME/$HADOOP_HDFS_HOME -- do you mean & (install both) or 
*or* just install one of the two?  This needs clarification--please remove the 
forward slash and replace it with what you're trying to say.  The audience here 
is complete newbie and they've been brought to this page from here: 
http://hadoop.apache.org/docs/r0.23.5/ (same with r2.0.2-alpha/) (quote: 
"Getting Started - The Hadoop documentation includes the information you need 
to get started using Hadoop. Begin with the Single Node Setup which shows you 
how to set up a single-node Hadoop installation."), they've downloaded 
hadoop-0.23.5.tar.gz and want to know what to do next.  Why are there 
potentially two applications -- hadoop-common and hadoop-hdfs and not just one? 
 (The download doesn't appear to have two separate apps) -- if there is indeed 
just one app and we remove the other from the above text to avoid confusion?

Again, I just downloaded hadoop-0.23.5.tar.gz -- do I need to download more?  
If so, let us know in the docs here.

Also, the fragment: "Assuming you have installed hadoop-common/hadoop-hdfs..."  
No, I haven't, that's what *this* page is supposed to explain to me how to do 
-- how do I install these two (or just one of these two)?

Also, what do I set $HADOOP_COMMON_HOME and/or $HADOOP_HDFS_HOME to?

4.) Quote: "NOTE: The following instructions assume you have hdfs running."  
No, I don't--how do I do this?  Again, this page is supposed to teach me that.

5.) Quote: "To start the ResourceManager and NodeManager, you will have to 
update the configs. Assuming your $HADOOP_CONF_DIR is the configuration 
directory..."

Could you clarify here what the "configuration directory" is, it doesn't exist 
in the 0.23.5 download.  I just see bin,etc,include,lib,libexec,sbin,share 
folders but no "conf" one.)

6.) Quote: "Assuming that the environment variables $HADOOP_COMMON_HOME, 
$HADOOP_HDFS_HOME, $HADOO_MAPRED_HOME, $YARN_HOME, $JAVA_HOME and 
$HADOOP_CONF_DIR have been set appropriately."

We'll need to know what to set YARN_HOME to here.

Thanks!
Glen

  Issue Type: Bug
Reporter: Ivan A. Veselovsky

Apacheds server is used in some security tests in Hadoop-common, hadoop-hdfs 
modules with "startKdc" profile.
The build script downloads the server, unpacks it, configures, and runs.

The problem is that used URL 
http://newverhost.com/pub//directory/apacheds/unstable/1.5/1.5.7/apacheds-1.5.7.tar.gz
 does not work any more (returns 404).

The suggested patch peremetrizes the URL, so that it can be set in single palce 
in the parent pom.xml, and sets it to the workable value.

Resolution: Won't Fix

For Windows, since the mainstream branch does not support it actively, am 
closing this as a Won't Fix.

I'm certain the same issue does not happen on the branch-1-win 1.x branch (or 
the branch-trunk-win branch), and I urge you to use that instead if you wish to 
continue using Windows for development or other usage. Find the 
Windows-optimized sources at 
http://svn.apache.org/repos/asf/hadoop/common/branches/branch-1-win/ or 
http://svn.apache.org/repos/asf/hadoop/common/branches/branch-trunk-win/.
