Dmitry Lysnichenko updated AMBARI-4481:
---------------------------------------
Description:
h1. Proposal:
h2. General conception
Ambari server shares some files at /var/lib/ambari-server/resources/ via HTTP.
These files are accessible via url like
http://hostname:8080/resources/jdk-6u31-linux-x64.bin . Among these files there
are service scripts, templates and hooks. Agent has a cache of these files.
Cache directory structure is similar to contents of a stacks folder at server.
For example:
$ ls /var/lib/ambari-agent/cache
{code}
└── stacks
└── HDP
├── 2.0.7
│ ├── Accumulo
│ └── Flume
└── 2.0.8
├── Accumulo
├── Flume
└── YetAnotherService
{code}
If files for some service, component and stack version is not available at
cache, agent downloads appropriate files on first use.
