Re: Integrating hadoop with java UI application deployed on tomcatJohn Hancock 2012-08-30, 09:36
You might need to put the apache commons configuration library jar in
web-inf/lib to clear this error.

Re: Integrating hadoop with java UI application deployed on tomcatHemanth Yamijala 2012-08-30, 10:35
Hi,
The error is talking about hadoop configuration. So probably you need to put the hadoop core jar in the lib folder. That said, there might be other dependencies you might need as well. But you can try it out once.

Re: Integrating hadoop with java UI application deployed on tomcatSteve Loughran 2012-08-30, 11:52
you will need almost the entire hadoop client-side JAR set and dependencies
for this, I'm afraid. The new webhdfs filesys -HDFS over HTTP- is designed to be lighter weight and only need an HTTP client, but I'm not aware of any ultra-thin client yet (apache http components should suffice). If you are using any of the build tools with dependency management: Ant+Ivy, Maven, Gradle, ask for Hadoop JARs and have the dependencies pulled in. If you aren't using any of the build tools w/ dependency management, now is the time.

Thanks steve thers nothing in logs and no exceptions as well i found that
some file is created in my F:\user with directory name but its not visible inside my hadoop browse filesystem directories i also added the config by using the below method hadoopConf.addResource("F:/hadoop-0.22.0/conf/core-site.xml"); when running thru WAR printing out the filesystem i m getting org.apache.hadoop.fs.LocalFileSystem@9cd8db when running an independet jar within hadoop i m getting DFS[DFSClient[clientName=DFSClient_296231340, ugi=dell]] when running an independet jar i m able to do uploads.... just wanted to know will i have to add something in my classpath of tomcat or is there any other configurations of core-site.xml that i am missing out..thanks for your help.....

If you are getting the LocalFileSystem, you could try by putting core-site.xml in a directory that's there in the classpath for the Tomcat App (or include such a path in the classpath, if that's possible) Thanks hemanth On Mon, Sep 3, 2012 at 4:01 PM, Visioner Sadak <[EMAIL PROTECTED]> wrote: > Thanks steve thers nothing in logs and no exceptions as well i found that > some file is created in my F:\user with directory name but its not visible > inside my hadoop browse filesystem directories i also added the config by > using the below method > hadoopConf.addResource( > "F:/hadoop-0.22.0/conf/core-site.xml"); > when running thru WAR printing out the filesystem i m getting > org.apache.hadoop.fs.LocalFileSystem@9cd8db > when running an independet jar within hadoop i m getting > DFS[DFSClient[clientName=DFSClient_296231340, ugi=dell]] > when running an independet jar i m able to do uploads.... > > just wanted to know will i have to add something in my classpath of tomcat > or is there any other configurations of core-site.xml that i am missing > out..thanks for your help..... > > > > On Sat, Sep 1, 2012 at 1:38 PM, Steve Loughran <[EMAIL PROTECTED]> > wrote: >> >> >> well, it's worked for me in the past outside Hadoop itself: >> >> >> http://smartfrog.svn.sourceforge.net/viewvc/smartfrog/trunk/core/hadoop-components/hadoop-ops/src/org/smartfrog/services/hadoop/operations/utils/DfsUtils.java?revision=8882&view=markup >> >> Turn logging up to DEBUG >> Make sure that the filesystem you've just loaded is what you expect, by >> logging its value.

Try using hadoopConf.addResource(*new
Path("F:/hadoop-0.22.0/conf/core-site.xml")*); instead of hadoopConf.addResource("F:/hadoop-0.22.0/conf/core-site.xml"); or you should add your core-site.xml to a location which is in your class path(WEB-INF\classes or WEB-INF\lib in case of a web application) On Mon, Sep 3, 2012 at 6:02 PM, Visioner Sadak <[EMAIL PROTECTED]>wrote: > thanks hemanth i tried adding ext folder conf and extn root folder > unable to add xml only but still same problem thanks for the help > > On Mon, Sep 3, 2012 at 4:11 PM, Hemanth Yamijala <[EMAIL PROTECTED]>wrote: > >> Hi, >> >> If you are getting the LocalFileSystem, you could try by putting >> core-site.xml in a directory that's there in the classpath for the >> Tomcat App (or include such a path in the classpath, if that's >> possible) >> >> Thanks >> hemanth >> >> On Mon, Sep 3, 2012 at 4:01 PM, Visioner Sadak <[EMAIL PROTECTED]> >> wrote: >> > Thanks steve thers nothing in logs and no exceptions as well i found >> that >> > some file is created in my F:\user with directory name but its not >> visible >> > inside my hadoop browse filesystem directories i also added the config >> by >> > using the below method >> > hadoopConf.addResource( >> > "F:/hadoop-0.22.0/conf/core-site.xml"); >> > when running thru WAR printing out the filesystem i m getting >> > org.apache.hadoop.fs.LocalFileSystem@9cd8db >> > when running an independet jar within hadoop i m getting >> > DFS[DFSClient[clientName=DFSClient_296231340, ugi=dell]] >> > when running an independet jar i m able to do uploads.... >> > >> > just wanted to know will i have to add something in my classpath of >> tomcat >> > or is there any other configurations of core-site.xml that i am missing >> > out..thanks for your help..... >> > >> > >> > >> > On Sat, Sep 1, 2012 at 1:38 PM, Steve Loughran <[EMAIL PROTECTED]> >> > wrote: >> >> >> >> >> >> well, it's worked for me in the past outside Hadoop itself: >> >> >> >> >> >> >> http://smartfrog.svn.sourceforge.net/viewvc/smartfrog/trunk/core/hadoop-components/hadoop-ops/src/org/smartfrog/services/hadoop/operations/utils/DfsUtils.java?revision=8882&view=markup >> >> >> >> Turn logging up to DEBUG >> >> Make sure that the filesystem you've just loaded is what you expect, by >> >> logging its value.

The error says call to 127.0.0.1:9000 fails. It is failing when it tries to
contact the namenode (9000 is the default namenode port) configured in core-site.xml. You should also check whether the namenode is configured correctly and also whether the namenode is up.

Re: Integrating hadoop with java UI application deployed on tomcatBejoy KS 2012-09-04, 10:08
Hi
You are running tomact on a windows machine and trying to connect to a remote hadoop cluster from there. Your core site has <name> fs.default.name</name> <value>hdfs://localhost:9000</value> But It is localhost here.( I assume you are not running hadoop on this windows environment for some testing) You need to have the exact configuration files and hadoop jars from the cluster machines on this tomcat environment as well. I mean on the classpath of your application.
