Taras Ledkov commented on IGNITE-2355:
--------------------------------------
Looks fine without p.3. I thing, that the parameter format is incompatible with
Hadoop configuration format. Hadoop HDFS HA & Cloudera HA configs uses the
addition level of indirect parameters like p.4. But there are not restriction
to implementation the p.3.
Also, I think p.3 and p.4 are mutually exclusive.
> Hadoop client should be able to failover in case of server crash.

> Project: Ignite
> Issue Type: Sub-task
> Components: hadoop
> Affects Versions: ignite-1.4
> Reporter: Vladimir Ozerov
> Assignee: Taras Ledkov
> Priority: Critical
> Labels: roadmap
> Fix For: 2.0

>
> Currently we explicitly specify a single IP address of Ignite server for map
> reduce.
> If it goes down, no jobs can be submitted anymore.
> Looks like we should give user ability to specify multiple addresses, and
> failover between them. Our thin client (which underlies Hadoop client) is
> already able to accept multiple addresses.
> Look at Hadoop HA first to get an ideas on how to configure multiple
> addresses.
