Probably configuration properties, according with HDFS HA & Cloudera map-reduce HA:
{code}
<property>

  <value>ignite0</value>
<!-- Possible values are a logical name of Ignite cluster or an address string  <host:port>
-->

> 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.
