Error after installing Hadoop-1.0.4

[Deepti Garg <dg...@dag.com>]

Hi,

 

I installed Hadoop 1.0.4 from this link on my Windows 7 machine using
cygwin:

http://hadoop.apache.org/docs/r1.0.4/single_node_setup.html

 

I am getting an error on running 

bin/hadoop jar hadoop-examples-*.jar grep input output 'dfs[a-z.]+'

 

Error:

cd: pattern "--" not found in "c:/cloudera/hadoop-1.0.4"

Warning: $HADOOP_HOME is deprecated.

I read in some other posts to add "CLASSPATH=`cygpath -wp "$CLASSPATH"`" to
hadoop-config.sh, but the error did not go away after adding it. 

 

I get this on running bin/hadoop:

cd: pattern "--" not found in "c:/cloudera/hadoop-1.0.4"

Warning: $HADOOP_HOME is deprecated.

  namenode             run the DFS namenode

  datanode             run a DFS datanode

 dfsadmin             run a DFS admin client

  mradmin              run a Map-Reduce admin client

  fsck                 run a DFS filesystem checking utility

  fs                   run a generic filesystem user client

  balancer             run a cluster balancing utility

  fetchdt              fetch a delegation token from the NameNode

  jobtracker           run the MapReduce job Tracker node

  pipes                run a Pipes job

  tasktracker          run a MapReduce task Tracker node

  historyserver        run job history servers as a standalone daemon

  job                  manipulate MapReduce jobs

  jar <jar>            run a jar file

  distcp <srcurl> <desturl> copy file or directories recursively

  archive -archiveName NAME -p <parent path> <src>* <dest> create a hadoop
archive

  classpath            prints the class path needed to get the

                       Hadoop jar and the required libraries

 daemonlog            get/set the log level for each daemon

or

  CLASSNAME            run the class named CLASSNAME

Most commands print help when invoked w/o parameters.

 

Any help is appreciated.
