Hello,
I recently built Ambari (specifically the ambari-186 branch) to evaluate its
current state. So far I have a web server running Ambari and I am at the step
where I am adding hosts to the Ambari server. I have deployed a public key on
all the target instances (all of which are RHEL 6.2 LXC containers with their
own IP address in an internal network) and I'm trying to get it to recognize
them.
During "Node Discovery", it was able to perform the following:
1) "Finding reachable nodes: All 5 nodes succeeded"
2) "Obtaining information about reachable nodes: All 5 nodes succeeded"
However it rejects my instances as having an unsupported OS. The host running
Ambari (localhost) is CentOS 6.2 and the nodes that are a part of a
Hadoop/HBase/ZooKeeper cluster are all RHEL 6.2 instances.
I checked the sqlite3 database /var/db/hmc/data/data.db and found this:
sqlite> .dump Hosts
PRAGMA foreign_keys=OFF;
BEGIN TRANSACTION;
CREATE TABLE "Hosts" (
cluster_name TEXT, -- foreign-key cluster_name
host_name TEXT, -- host name
ip TEXT, -- ip
total_mem INTEGER, -- total mem on host - in bytes
cpu_count INTEGER, -- cpu count - no. of cores
os_arch TEXT, -- os arch - i386, x86_64 etc
os_type TEXT, -- os type - searchable - defined set of supported OS types -
RHEL5, RHEL6, CENTOS5, SLES, etc.
os BLOB, -- os info - type, version etc - uname -a?
disks_info BLOB, -- disk capacity json object, keys are mount-points
discovery_status TEXT, -- discovery state - if we could connect properly
bad_health_reason TEXT, -- failure reason if any
rack_info TEXT, -- rack information for host
attributes BLOB, -- attributes blob to store additional attributes that may
be required for the host
-- attributes stored currently:

UNIQUE(ip)
);

CREATE INDEX host_mem_index ON "Hosts" ( total_mem );

How much work could it possibly be to manually (fully) add RHEL 6 support if I
add RHEL 6 and CentOS 6 to the supported OS types here? I added CentOS and
RHEL 6 to the list of supported OS types and now it is looking to add the EPEL
repo for CentOS 5.
/usr/share/hmc/php/frontend/addNodes/verifyAndUpdateNodesInfo.php
Is Ambari currently only supporting the CentOS/RHEL 5/SuSE 10 series of Linux
distributions?
Thanks!
