The name of the default file system. Either the
literal string "local" or a host:port for DFS.
mapred.job.tracker
dbrg-1:9001
The host and port that the MapReduce job tracker
runs at. If "local", then jobs are run in-process as a single map and
reduce task.
hadoop.tmp.dir
/home/dbrg/HadoopInstall/tmp
A base for other temporary directories.
dfs.name.dir
/home/dbrg/HadoopInstall/filesystem/name
Determines where on the local filesystem the DFS
name node should store the name table. If this is a comma-delimited
list of directories then the name table is replicated in all of the
directories, for redundancy.
dfs.data.dir
/home/dbrg/HadoopInstall/filesystem/data
Determines where on the local filesystem an DFS data
node should store its blocks. If this is a comma-delimited list of
directories, then data will be stored in all named directories,
typically on different devices. Directories that do not exist are
ignored.
dfs.replication
1
Default block replication. The actual number of
replications can be specified when the file is created. The default is
used if replication is not specified in create time.
