Instructions on how to run Apache Hadoop 2.0.2-alpha?

[Glen Mazza <gm...@talend.com>]

Hi, I was able to run Hadoop 1.0.4 single-node with no difficulty 
following these instructions: 
http://hadoop.apache.org/docs/stable/single_node_setup.html .

The corresponding page that we're referred to at the bottom of here: 
http://hadoop.apache.org/docs/current/ for Hadoop 2.0.2 is radically 
different, however, it doesn't seem to have anything to do with starting 
Hadoop: 
http://hadoop.apache.org/docs/current/hadoop-yarn/hadoop-yarn-site/SingleCluster.html 
.  Is it because I'm looking at the wrong page or is it that Hadoop 
2.0.2 is really so different that the instructions have radically 
changed?  Is there anything similar to 
http://hadoop.apache.org/docs/stable/single_node_setup.html that will 
show me how to run Hadoop 2.0.2?

Thanks,
Glen

Re: Instructions on how to run Apache Hadoop 2.0.2-alpha?

[Robert Evans <ev...@yahoo-inc.com>]

It is very long and confusing. Here is my understanding of what happened even though I was not around for all of it.

0.1 - 0.20 was mostly main line development.  At that point there was a split and 0.20 was forked to add security, 0.20-security, and also to add in append support for H-BASE 0.20-append.  For a long time these branches were maintained and has bug fixes added to it while main line development went on with 0.21 and 0.22.  0.20-security was merged with 0.20-append and was renamed 1.0.  It has continued with bug fixes and some new feature work back ported from trunk.

But development did not stop at 0.22.  0.23 was created to support YARN/MR-V2.  At about the same time 0.24 was made for trunk.  When 0.20-security+append became 1.0, 0.23 became 2.0 and 0.24 became 3.0.  We at Yahoo! Have been in the process of stabilizing YARN for about a year or so.  Because 2.0 looked like new features were going to continue to go in we decided to keep 0.23 alive for stabilization purposes while 2.0 continued on.  It has since gotten several new features like HDFS-HA and protocol buffer based RPC for HDFS, and a few new features for YARN/MR.  So you can almost think of 0.23 as 2.0--.  We hope to move to 2.0 in the near future once it stabilizes and loses the alpha tag, at which point 0.23 would go away.

OK, looking at the Hadoop branches: http://svn.apache.org/viewvc/hadoop/common/branches/ and tags: http://svn.apache.org/viewvc/hadoop/common/tags/, it's thankfully not that bad.
There is no 0.24 in Hadoop, and the Maven pom files for the 2.0.2-alpha branch indeed say 2.0.2-alpha.  The Cloudera article linked to below mentions 0.24, but it's from 2011 and may have been at a time before the Hadoop team decided to relabel to 2.0 instead.

Hi, I was able to run Hadoop 1.0.4 single-node with no difficulty following these instructions:  http://hadoop.apache.org/docs/stable/single_node_setup.html .

The corresponding page that we're referred to at the bottom of here: http://hadoop.apache.org/docs/current/ for Hadoop 2.0.2 is radically different, however, it doesn't seem to have anything to do with starting Hadoop:  http://hadoop.apache.org/docs/current/hadoop-yarn/hadoop-yarn-site/SingleCluster.html .  Is it because I'm looking at the wrong page or is it that Hadoop 2.0.2 is really so different that the instructions have radically changed?  Is there anything similar to http://hadoop.apache.org/docs/stable/single_node_setup.html that will show me how to run Hadoop 2.0.2?

Re: Instructions on how to run Apache Hadoop 2.0.2-alpha?

[Robert Evans <ev...@yahoo-inc.com>]

It is very long and confusing. Here is my understanding of what happened even though I was not around for all of it.

0.1 - 0.20 was mostly main line development.  At that point there was a split and 0.20 was forked to add security, 0.20-security, and also to add in append support for H-BASE 0.20-append.  For a long time these branches were maintained and has bug fixes added to it while main line development went on with 0.21 and 0.22.  0.20-security was merged with 0.20-append and was renamed 1.0.  It has continued with bug fixes and some new feature work back ported from trunk.

But development did not stop at 0.22.  0.23 was created to support YARN/MR-V2.  At about the same time 0.24 was made for trunk.  When 0.20-security+append became 1.0, 0.23 became 2.0 and 0.24 became 3.0.  We at Yahoo! Have been in the process of stabilizing YARN for about a year or so.  Because 2.0 looked like new features were going to continue to go in we decided to keep 0.23 alive for stabilization purposes while 2.0 continued on.  It has since gotten several new features like HDFS-HA and protocol buffer based RPC for HDFS, and a few new features for YARN/MR.  So you can almost think of 0.23 as 2.0--.  We hope to move to 2.0 in the near future once it stabilizes and loses the alpha tag, at which point 0.23 would go away.

OK, looking at the Hadoop branches: http://svn.apache.org/viewvc/hadoop/common/branches/ and tags: http://svn.apache.org/viewvc/hadoop/common/tags/, it's thankfully not that bad.
There is no 0.24 in Hadoop, and the Maven pom files for the 2.0.2-alpha branch indeed say 2.0.2-alpha.  The Cloudera article linked to below mentions 0.24, but it's from 2011 and may have been at a time before the Hadoop team decided to relabel to 2.0 instead.  Looking at this again: http://hadoop.apache.org/docs/r2.0.2-alpha/hadoop-yarn/hadoop-yarn-site/SingleCluster.html, it appears to provide workable instructions, I'll try again with it.  Thanks for your assistance.

Hi Glen

I agree with you. There are many versions and confusing. If you really want to know, you can check the developing and publishing documents. In 0.23's document, they must announced how many patches are included, as well as the 2.0.x.

Then you will exactly understand which one is which one.

Also the releases page: http://hadoop.apache.org/releases.html mentions *both* 0.23.x and 2.0.2 releases -- wouldn't the former be numbered as the latter, if as you're saying, 0.23 is published as 2.0.x?

Hi, I was able to run Hadoop 1.0.4 single-node with no difficulty following these instructions:  http://hadoop.apache.org/docs/stable/single_node_setup.html .

The corresponding page that we're referred to at the bottom of here: http://hadoop.apache.org/docs/current/ for Hadoop 2.0.2 is radically different, however, it doesn't seem to have anything to do with starting Hadoop:  http://hadoop.apache.org/docs/current/hadoop-yarn/hadoop-yarn-site/SingleCluster.html .  Is it because I'm looking at the wrong page or is it that Hadoop 2.0.2 is really so different that the instructions have radically changed?  Is there anything similar to http://hadoop.apache.org/docs/stable/single_node_setup.html that will show me how to run Hadoop 2.0.2?

Thanks,

Re: Instructions on how to run Apache Hadoop 2.0.2-alpha?

[Glen Mazza <gm...@talend.com>]

OK, looking at the Hadoop branches: 
http://svn.apache.org/viewvc/hadoop/common/branches/ and tags: 
http://svn.apache.org/viewvc/hadoop/common/tags/, it's thankfully not 
that bad.
There is no 0.24 in Hadoop, and the Maven pom files for the 2.0.2-alpha 
branch indeed say 2.0.2-alpha.  The Cloudera article linked to below 
mentions 0.24, but it's from 2011 and may have been at a time before the 
Hadoop team decided to relabel to 2.0 instead.  Looking at this again: 
http://hadoop.apache.org/docs/r2.0.2-alpha/hadoop-yarn/hadoop-yarn-site/SingleCluster.html, 
it appears to provide workable instructions, I'll try again with it.  
Thanks for your assistance.

Re: Instructions on how to run Apache Hadoop 2.0.2-alpha?

[Chen He <ai...@gmail.com>]

Hi Glen

I agree with you. There are many versions and confusing. If you really want
to know, you can check the developing and publishing documents. In 0.23's
document, they must announced how many patches are included, as well as the
2.0.x.

Then you will exactly understand which one is which one.

Re: Instructions on how to run Apache Hadoop 2.0.2-alpha?

[Glen Mazza <gm...@talend.com>]

Thanks for your response.  That's pretty vital information--I'm not used 
to separate development/publication versions.  Is the 0.23-->2.0.2 
renumbering stated anywhere on the Hadoop website or wiki?  It's very 
confusing as people otherwise think there are three separate branches -- 
0.2x.y, 1.x, and 2.x when there are really just two.

Also the releases page: http://hadoop.apache.org/releases.html mentions 
*both* 0.23.x and 2.0.2 releases -- wouldn't the former be numbered as 
the latter, if as you're saying, 0.23 is published as 2.0.x?

Thanks,
Glen

0.24 is the developing version, 2.0.2 is the publication version.

The corresponding page that we're referred to at the bottom of here: http://hadoop.apache.org/docs/current/ for Hadoop 2.0.2 is radically different, however, it doesn't seem to have anything to do with starting Hadoop:  http://hadoop.apache.org/docs/current/hadoop-yarn/hadoop-yarn-site/SingleCluster.html .
