Re: Problems

Thanks -- that would explain why I have not got into trouble yet as I am 
only using
MR and HDFS.

Some of the unit tests fail with 1.7. HDFS and MR mostly work OK, but
if you run into problems with 1.7 the first question will be "does it
work in 1.6?".

Do you know what causes 1.7 to fail? I am running 1.7 and so far have not
done whatever it takes to make it fail.

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?

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?

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.
