Hi,
Not sure if this is a BigTop issue or if I should report this to the
MapReduce project. Pointers appreciated!
This is related to https://issues.apache.org/jira/browse/BIGTOP-460
https://svn.apache.org/viewvc?view=revision&revision=1235956 erroneously
removed the jobtracker and tasktracker commands without providing
replacement functionality. The change points to the yarn command but that
script doesn't provide MRv1 support.
The hadoop command, when invoked as 'hadoop jobtracker', says
DEPRECATED: Use of this script to execute mapred command is deprecated.
Instead use the mapred command for it.
But `mapred jobtracker' says:
Sorry, the jobtracker command is no longer supported.
you may find similar functionality with the "yarn" shell command.
Usage: mapred [--config confdir] COMMAND
where COMMAND is one of:
pipes run a Pipes job
job manipulate MapReduce jobs
queue get information regarding JobQueues
classpath prints the class path needed for running
mapreduce subcommands
groups get the groups which users belong to
historyserver run job history servers as a standalone daemon
distcp <srcurl> <desturl> copy file or directories recursively
archive -archiveName NAME -p <parent path> <src>* <dest> create a hadoop
archive
Most commands print help when invoked w/o parameters.
Thanks for any help/insight you may be able to provide.
Cheers,
Jos
Hi Jos,
I am not sure I fully understand your issue, but the jobtracker and
tasktracker do not exist anymore in Apache Hadoop 2.0.
See
http://hadoop.apache.org/common/docs/current/hadoop-yarn/hadoop-yarn-site/YARN.html
Thanks,
Bruno
