Re: HBase and Apache Jena -SLF4J Conflict

[Ted Yu <yu...@gmail.com>]

Which HBase version are you using ?

In 0.94, I see the following in pom.xml:

<slf4j.version>1.4.3</slf4j.version>
...
        <hadoop.version>1.0.4</hadoop.version>
        <slf4j.version>1.4.3</slf4j.version>
The line above is for hadoop-1.0 profile. You can selectively override
SLF4J version so that it is consistent across both projects.

Cheers

Re: HBase and Apache Jena -SLF4J Conflict

[Kiran <ki...@gmail.com>]

First of all I would like to make it clear that I'am not using Maven for my
project.In netbeans IDE I'am creating an ordinary Java project and imporitng
all libraries in lib folders of HBase, Hadoop and Jena.The versions I'am
using are:

HBase: 0.90.6
Hadoop: 0.20.2
Jena: 2.7.4

{HBase and Hadoop  part of CDH3U5}
