Problems

[Sean Hudson <se...@ostiasolutions.com>]

Hi,
      I have recently installed hadoop-1.0.4 on a linux machine. Whilst working through the post-install instructions contained in the “Quick Start” guide, I incurred the following catastrophic Java runtime error (See below). I have attached the error report file “hs_err_pid24928.log”. I have submitted a Java bug report, but perhaps it is a known hadoop-1.0.4 version problem.

I am a first time user of Hadoop and would welcome guidance on this problem,

Regards,

Sean Hudson.

I wouldn't call it validation since all I am running are examples. it is 
more likely to be I haven't yet run into the brick wall that
others have already found!

Hi Ke,
            We are still looking at possible complications of the VM environment. I will post whatever we discover.

Thanks for your interest,

is there anything done with hardware? i used thinkpad t430,this problem occurs,but i used about 100 machines ,there is nothing to do  with this ,all the machines is redhat 6.0,and the jdk is jdk1.5 to jdk1.6 , so i think there is something to do with the hardware，any idea?

  Hi Sean,

  Will you be able to run the memtest86 on this VM? Maybe it's an issue
  with the way the VM is managing the memory?

  I ran HBase+Hadoop on a desktop with only 1.5G. So you should not have
  any issue with 6GB.

  I don't think the issue you are facing is related to hadoop. Can you
  try to run a simple Java application in you JVM? Something which will
  use lot of memory. And see if it works?

Hi Ke,
            We are still looking at possible complications of the VM environment. I will post whatever we discover.

Thanks for your interest,

is there anything done with hardware? i used thinkpad t430,this problem occurs,but i used about 100 machines ,there is nothing to do  with this ,all the machines is redhat 6.0,and the jdk is jdk1.5 to jdk1.6 , so i think there is something to do with the hardware，any idea?


2013/1/22 Jean-Marc Spaggiari <je...@spaggiari.org>

  Hi Sean,

  Will you be able to run the memtest86 on this VM? Maybe it's an issue
  with the way the VM is managing the memory?

  I ran HBase+Hadoop on a desktop with only 1.5G. So you should not have
  any issue with 6GB.

  I don't think the issue you are facing is related to hadoop. Can you
  try to run a simple Java application in you JVM? Something which will
  use lot of memory. And see if it works?

Re: Problems

[ke yuan <ke...@gmail.com>]

is there anything done with hardware? i used thinkpad t430,this problem
occurs,but i used about 100 machines ,there is nothing to do  with this
,all the machines is redhat 6.0,and the jdk is jdk1.5 to jdk1.6 , so i
think there is something to do with the hardware，any idea?

Re: Problems

[ke yuan <ke...@gmail.com>]

is there anything done with hardware? i used thinkpad t430,this problem
occurs,but i used about 100 machines ,there is nothing to do  with this
,all the machines is redhat 6.0,and the jdk is jdk1.5 to jdk1.6 , so i
think there is something to do with the hardware，any idea?

Re: Problems

[Jean-Marc Spaggiari <je...@spaggiari.org>]

Hi Sean,

Will you be able to run the memtest86 on this VM? Maybe it's an issue
with the way the VM is managing the memory?

I ran HBase+Hadoop on a desktop with only 1.5G. So you should not have
any issue with 6GB.

I don't think the issue you are facing is related to hadoop. Can you
try to run a simple Java application in you JVM? Something which will
use lot of memory. And see if it works?

Re: Problems

[Jean-Marc Spaggiari <je...@spaggiari.org>]

Hi Sean,

Will you be able to run the memtest86 on this VM? Maybe it's an issue
with the way the VM is managing the memory?

I ran HBase+Hadoop on a desktop with only 1.5G. So you should not have
any issue with 6GB.

I don't think the issue you are facing is related to hadoop. Can you
try to run a simple Java application in you JVM? Something which will
use lot of memory. And see if it works?

Re: Problems

[Sean Hudson <se...@ostiasolutions.com>]

Hi Jean-Marc,
                        The Linux machine on which I am attempting to get 
Hadoop running is actually Linux running in a VM partition. This VM 
partition had 2 Gigs of RAM when I first encountered the problem. This RAM 
allocation has been bumped up to 6 Gigs, but the problem still persists, i.e

bin/hadoop jar hadoop-*-examples.jar grep input output 'dfs[a-z.]+'  still 
crashes out as before.

Is there a minimum RAM size requirement?
Will Hadoop run correctly on Linux in a VM partition?

                        I had attempted to run Hadoop in Pseudo-Distributed 
Operation mode and this included modifying the conf/core-site.xml, 
conf/hdfs-site.xml and the conf/mapred-site.xml files as per the Quick Start 
instructions. I also formatted a new distributed-filesystem as per the 
instructions. To re-test in Standalone mode with 6 Gigs of RAM, I reversed 
the changes to the above three .xml files in /conf. However, I don't see a 
way to back-out the distributed-filesystem. Will the existence of this 
distributed-filesystem interfere with my Standalone tests?

Regards,

Sean Hudson

Hi Sean,

It's strange. You should not faced that.  I faced same kind of issues

Re: Problems

[Sean Hudson <se...@ostiasolutions.com>]

Hi Jean-Marc,
                        The Linux machine on which I am attempting to get 
Hadoop running is actually Linux running in a VM partition. This VM 
partition had 2 Gigs of RAM when I first encountered the problem. This RAM 
allocation has been bumped up to 6 Gigs, but the problem still persists, i.e

bin/hadoop jar hadoop-*-examples.jar grep input output 'dfs[a-z.]+'  still 
crashes out as before.

Is there a minimum RAM size requirement?
Will Hadoop run correctly on Linux in a VM partition?

                        I had attempted to run Hadoop in Pseudo-Distributed 
Operation mode and this included modifying the conf/core-site.xml, 
conf/hdfs-site.xml and the conf/mapred-site.xml files as per the Quick Start 
instructions. I also formatted a new distributed-filesystem as per the 
instructions. To re-test in Standalone mode with 6 Gigs of RAM, I reversed 
the changes to the above three .xml files in /conf. However, I don't see a 
way to back-out the distributed-filesystem. Will the existence of this 
distributed-filesystem interfere with my Standalone tests?

Regards,

Sean Hudson

Hi Sean,

It's strange. You should not faced that.  I faced same kind of issues
on a desktop with memory errors. Can you install memtest86 and fullty
test your memory (one pass is enought) to make sure you don't have

Hi Sean,

It's strange. You should not faced that.  I faced same kind of issues
on a desktop with memory errors. Can you install memtest86 and fullty
test your memory (one pass is enought) to make sure you don't have

Hi Sean,

It's strange. You should not faced that.  I faced same kind of issues
on a desktop with memory errors. Can you install memtest86 and fullty
test your memory (one pass is enought) to make sure you don't have
issues on that side?

Re: Problems

[Sean Hudson <se...@ostiasolutions.com>]

Leo,
        I downloaded the suggested 1.6.0_32 Java version to my home 
directory, but I am still experiencing the same problem (See error below).
The only thing that I have set in my hadoop-env.sh file is the JAVA_HOME 
environment variable. I have also tried it with the Java directory added to 
PATH.

export JAVA_HOME=/home/shu/jre1.6.0_32
export PATH=$PATH:/home/shu/jre1.6.0_32

Every other environment variable is defaulted.

Just to clarify, I have tried this in Local Standalone mode and also in 
Pseudo-Distributed Mode with the same result.

Frustrating to say the least,

Sean Hudson

Hi Sean,

This is an issue with your JVM. Not related to hadoop.

Which JVM are you using, and can you try with the last from Sun?

Re: Problems

[Sean Hudson <se...@ostiasolutions.com>]

Leo,
        I downloaded the suggested 1.6.0_32 Java version to my home 
directory, but I am still experiencing the same problem (See error below).
The only thing that I have set in my hadoop-env.sh file is the JAVA_HOME 
environment variable. I have also tried it with the Java directory added to 
PATH.

export JAVA_HOME=/home/shu/jre1.6.0_32
export PATH=$PATH:/home/shu/jre1.6.0_32

Every other environment variable is defaulted.

Just to clarify, I have tried this in Local Standalone mode and also in 
Pseudo-Distributed Mode with the same result.

Frustrating to say the least,

Sean Hudson

Hi Sean,

This is an issue with your JVM. Not related to hadoop.

Which JVM are you using, and can you try with the last from Sun?

RE: Problems

[Leo Leung <ll...@ddn.com>]

Use Sun/Oracle  1.6.0_32+   Build should be 20.7-b02+

1.7 causes failure and AFAIK,  not supported,  but you are free to try the latest version and report back.

Hi,
      My Java version is

java version "1.6.0_25"
Java(TM) SE Runtime Environment (build 1.6.0_25-b06) Java HotSpot(TM) Client VM (build 20.0-b11, mixed mode, sharing)

Would you advise obtaining a later Java version?

Hi Sean,

This is an issue with your JVM. Not related to hadoop.

Which JVM are you using, and can you try with the last from Sun?

Hi,
      My Java version is

java version "1.6.0_25"
Java(TM) SE Runtime Environment (build 1.6.0_25-b06)
Java HotSpot(TM) Client VM (build 20.0-b11, mixed mode, sharing)

Would you advise obtaining a later Java version?

Hi Sean,

This is an issue with your JVM. Not related to hadoop.

Which JVM are you using, and can you try with the last from Sun?

Hi,
      My Java version is

java version "1.6.0_25"
Java(TM) SE Runtime Environment (build 1.6.0_25-b06)
Java HotSpot(TM) Client VM (build 20.0-b11, mixed mode, sharing)

Would you advise obtaining a later Java version?

Sean

Hi Sean,

This is an issue with your JVM. Not related to hadoop.

Which JVM are you using, and can you try with the last from Sun?
