I've been trying to install hive in hadoop and this error pops out, Does anybody have any idea what does this means?
The issue is because you are using Hadoop3 which is still in second alpha test stage, simple solution is remove it and install hadoop2.7.3
The issue might be because of the incompatibility between your Hive version and the Hadoop version. Hadoop3 is very latest and Hive 0.12 is very old version. So you can either try upgrading your hive to any of the latest versions like Hive2.1.1 or you can try downgrading your Hadoop version to Hadoop2.x.

I am getting started with hadoop. I installed java. Set Java_Home to 1.8 and installed hadoop.2.7.6 and I cd'ed into the hadoop installation directory to run bin/hadoop. How ever I donot see any output. I have also tried one of the examples using the command
bin/hadoop jar share/hadoop/mapreduce/hadoop-mapreduce-examples-2.7.6.jar
Initially
Appreciate your help.
It looks like there is some issue with version 2.7.6. I installed version 2.7.7 and it started to work.
I'm running debian. I'm new to Hadoop. Sometime back, I was trying to install Hadoop. I'm not sure if I've successfully installed. When I enter command at terminal
hadoop version
I see the output:
Hadoop 2.7.1
Subversion https://git-wip-us.apache.org/repos/asf/hadoop.git -r 15ecc87ccf4a0228f35af08fc56de536e6ce657a

Compiled with protoc 2.5.0

This command was run using /home/xxxxxxx/java/hadoop-2.7.1/share/hadoop/common/hadoop-common-2.7.1.jar
Is hadoop installed properly? If not, what other tests I've to do? If yes, is there some simple "get-started" tutorial/exercise you're aware of, that can help me get started with?
Thank you!
I have no other option than to install HBase 0.90.6 as it is only recommended stable version for Nutch (web crawler) other than 0.90.4.
My question, which Hadoop version is recommended for HBase 0.90.6 to work on pseudo distributed mode?
I figured out Hadoop 0.20.205.0 is the compatible version.
I tried Hadoop 1.2.1 but it doesn't seem to work well with HBase 0.90.6
I have a Hadoop cluster with version 1.2.1 and recently i also downloaded hbase 0.94.11 to try out. I able to setup hbase t run in distributed mode but when i checked the web gui status, it stated that the Hadoop version is 1.0.4. I noticed that this is because hbase use the hadoop-core-1.0.4.jar file comes together with hbase. So my question is should i replace this jar file with the hadoop-core-1.2.1.jar so that hbase can use the latest hadoop-core jar file? And does it matter?
Cw
You don't have to do that if 1.0.4 works for you. Because the newest version may bring you any other problems and just replace hadoop-core.jar is unsafe. If you want to upgrade the HBase, please follow the official guide.
Hope it helps.
I'm using hadoop 1.0.4 and hive 0.9.0
can any one suggest which version of Sqoop we can configure?
I would recommend using latest Sqoop version 1.4.2. You can get the bits from official mirror. Please make sure to download file ending with "hadoop-1.0.0.tar.gz" that contains binary artifact compatible with your Hadoop release.
