Subject [jira] [Commented] (HADOOP-11315) Cannot compile Hadoop Code
Date Fri, 21 Nov 2014 10:16:34 GMT

Anand Murali commented on HADOOP-11315:

Dear Steve:
Many thanks for your response. This is deeply appreciated. Assuming, I use Eclipse, Kepler
to do write code and compile, I still need to configure Hadoop to talk to Keepler. I am having
problems just starting the daemons, how do I get help to fix this and also configure Kepler
to Hadoop-2.2.0. I have done google search on these issues without much use. Your advise is
deeply appreciated.

Steve Loughran resolved HADOOP-11315.
    Resolution: Invalid

Anand, please look at the [Invalid JIRA Issue|http://wiki.apache.org/hadoop/InvalidJiraIssues]
wiki page and recognise that these and the other JIRAs you are filing are not considered problems
in the Hadoop codebase. 

# Nobody is going to help you via the JIRAs, it is not a support site. 
# The users mailing list is the probably the only place that is going to help you. Subscribe

# Your issue here isn't even a hadoop problem, its a "Java classpath for compiling code" problem.
Nobody tries to compile java code on the command line like this, precisely because it is impossible
to get the classpath right. Either download an IDE and set it up, or download a build tool
like [Apache Maven|http://maven.apache.org/] and set up a command line build that works.

above and still errors out. However, on typing "hadoop version". it runs and picks up the
required jars in share.. Have raised this issue a coupld of times in the last 1 week and it
is closed as not replicable. But issue persists. Checked on user forums, but no help. Request
