Jagane Sundar commented on HADOOP-7417:
---------------------------------------
Let me expand a little bit on Eric's explanation:
HMS is a full lifecycle management system for Hadoop. It can create hadoop
clusters, automatically manage the configuration of hadoop clusters, tear down
hadoop clusters and upgrade hadoop clusters.
HMS consists of highly available HMS Controller(s). A HMS Agent on each Hadoop
Node communicates with the HMS Controller(s). HMS Users issue commands to the
HMS Controller using a REST API. Example commands can
create/teardown/configure/upgrade Hadoop clusters.
HMS aspires to use OS native packaging mechanisms for installing hadoop, i.e.
rpms on RedHat, .debs on Debian/Ubu. tarball installation for unsupported Unix
like operating systems is also supported.
HMS differs from Chef/Puppet and other deployment frameworks in several
important ways.
1. HMS is built to be highly available from day 1. HMS controllers can die and
be restarted. HMS Agents and the machines they run on can spontaneously reboot.
HMS itself will continue to be available.
2. HMS is meant to scale to the size of a 20,000 plus server Datacenter.
3. HMS is designed to be the building block for constructing a self service
Hadoop cloud, wherein users can create/configure/teardown Hadoops.
