Shubhangi Garg created HDFS-4552:
------------------------------------
Summary: For Hadoop 2.0.3; setting CLASSPATH=$(hadoop classpath)
does not work, as opposed to 1.x versions
Key: HDFS-4552
URL: https://issues.apache.org/jira/browse/HDFS-4552
Project: Hadoop HDFS
Issue Type: Bug
Components: libhdfs
Affects Versions: 2.0.3-alpha
Environment: Ubuntu 12.04 32 bit, java version "1.7.0_03"
c++ application
Reporter: Shubhangi Garg
I am writing an application in c++, which uses API provided by libhdfs to
manipulate Hadoop DFS.
I could run the application with 1.0.4 and 1.1.1; setting classpath equal to
$(hadoop classpath).
For Hadoop 2.0.3; setting CLASSPATH=$(hadoop classpath) does not load necessary
classes required forlibhdfs; as opposed to 1.x versions; giving the following
error:
loadFileSystems error:
(unable to get stack trace for java.lang.NoClassDefFoundError exception:
ExceptionUtils::getStackTrace error.)
hdfsBuilderConnect(forceNewInstance=0, nn=default, port=0,
kerbTicketCachePath=(NULL), userName=(NULL)) error:
(unable to get stack trace for java.lang.NoClassDefFoundError exception:
ExceptionUtils::getStackTrace error.)
I tried loading the jar files with their full path specified (as opposed to
wildcard characters used in the classpath); and the application runs, but gives
the following warning:
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further
details.
