Subject Re: Errors running Hadoop 2.2.0 on Cygwin
Date Mon, 25 Nov 2013 19:41:09 GMT
added echo $CLASSPATH in libexec/hadoop-config.sh and here is what it
contains


C:\hadoop-2.2.0\etc\hadoop;C:\hadoop-2.2.0\share\hadoop\common\lib\*;C:\hadoop-2.2.0\share\hadoop\common\*:/cygdrive/c/hadoop-2.2.0/share/hadoop/hdfs:/cygdrive/c/hadoop-2.2.0/share/hadoop/hdfs/lib/*:/cygdrive/c/hadoop-2.2.0/share/hadoop/hdfs/*:/cygdrive/c/hadoop-2.2.0/share/hadoop/yarn/lib/*:/cygdrive/c/hadoop-2.2.0/share/hadoop/yarn/*:/cygdrive/c/hadoop-2.2.0/share/hadoop/mapreduce/lib/*:/cygdrive/c/hadoop-2.2.0/share/hadoop/mapreduce/*:/cygdrive/c/hadoop-2.2.0//contrib/capacity-scheduler/*.jar

I can clearly see windows paths in the  classpath. I think is the reason
for the issue. But I haven't mentioned anything expilcitly with windows
based paths

this is what is mentioned in my ~/.bashrc file

export HADOOP_HOME=/cygdrive/c/hadoop-2.2.0/
export HADOOP_MAPRED_HOME=/cygdrive/c/hadoop-2.2.0
export HADOOP_COMMON_HOME=/cygdrive/c/hadoop-2.2.0
export HADOOP_HDFS_HOME=/cygdrive/c/hadoop-2.2.0
export YARN_HOME=/cygdrive/c/hadoop-2.2.0
export HADOOP_CONFIG_DIRECTORY=/cygdrive/c/hadoop-2.2.0/etc/hadoop
