Added floating IP feature

DcsMaster backups are configured in the conf/backup-masters file.

Whenever a backup takes over it now executes the bin/scripts/dcsbind.sh

script to move the floating IP to its own node. There are 3 new

properties necessary. They are:

dcs.master.floating.ip

Disabled by default. This property is used to enable/disable the

the floating IP feature.

dcs.master.floating.ip.external.interface

There is no default. The user must specify the network interface

to use for floating ip.

dcs.master.floating.ip.external.ip.address

There is no default. The user must specify the dotted IP

address to use for floating ip.

Patch set #2

removed hostname from backup-masters file

cleaned up trailing spaces

Patch set #3

updated copyrights

Manageability changes in DCS

1) Port mapping

At startup DcsMaster now creates a list of TCP/IP ports based on the

entries in the conf/servers file and writes it to the zookeeper

/<username>/trafodion/dcs/servers/registered znode. Each MXOSRVR reads

the port map list and retrieves its unique port number.

2) Trafodion repository

JDBC type4 is used to access SQL from DcsMaster. The feature is disabled

by default but may be enabled by overriding the unpublished

"dcs.master.trafodion.repository" property with a value of .true. in

your dcs-site.xml file.

3) HA for DcsMaster

A new file, /bin/master-backup.sh, was added that when called from

dcs-start/dcs-stop script look for the presence of optional

/conf/backup-masters file. This feature works like the existing

.servers. in that you can specify hostnames, one per line, e.g.,

.localhost.. The script will start/stop DcsMaster processes on all hosts

defined in the file. The DcsMaster has new leader election code so that

only one DcsMaster process is the .leader.. All others wait, in a

non-herding fashion, for other DcsMasters to fail. The vision is that

the Seaquest .ndcsbind. script may be run prior to starting DCS but

more effort is needed to test this. This commit sets up the

infrastructure. There.s no property for this feature as it.s enabled

only the /conf/backup-masters file exists and has host names defined.

4) Trafodion logs

As a convenience DcsMaster can display the Trafodion log files found in

$MY_SQROOT/logs. There was no requirement for this rather I added for my

development use. Be warned that DcsMaster is not aware of Trafodion

configuration changes so right now it only looks in $MY_SQROOT/logs.

This feature is disabled by default but may be enabled by overriding the

unpublished "dcs.master.trafodion.logs" property with a value of .true.

in your dcs-site.xml file.

5) Basic Security

Provide basic infrastructure to authenticate DcsMaster Web UI users. A

new file /conf/realm.properties was added as a first step. It allows for

definition of users with roles. The embedded Jetty web server reads this

file and uses it to authenticate users attempting to access the

DcsMaster web UI. This feature will surely change over time. It also

supports #3 above as we need username/password for the connection to SQL

in T4 driver. We want users to only see/cancel their own queries. This

feature is disabled by default but may be enabled by overriding the

unpublished "dcs.master.security" property with a value of .true. in

your dcs-site.xml file.
