> Problem: Load performance degrade by fixing task distribution issue.
> Cause: Consider 3 node cluster (host name a,b,c with IP1, IP2, IP3 as ip
> address), to launch load task, host name is required from
> NewCarbonDataLoadRDD in getPreferredLocations(). But if the driver is a
> (IP1),
> result is IP1, b,c instead of a,b,c. Hence task was not launching to one
> executor which is same ip as driver.
> getLocalhostIPs is modified in current version recently and instead of IP it
> was returning address, hence local ip hostanme was removed instead of address.
> solution: Revert the change in getLocalhostIPs as it is not used in any other
> flow.
