Subject [jira] [Updated] (IGNITE-2355) Hadoop client should be able to failover in case of server crash.
Date Mon, 11 Jan 2016 10:17:39 GMT

     [ https://issues.apache.org/jira/browse/IGNITE-2355?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Vladimir Ozerov updated IGNITE-2355:
------------------------------------
    Description: 
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.
