HyperTable - MapReduce API doesn't work on Xen/EC2 #127

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
The MapReduce jar file can't find the master node when running in Xen or
EC2 (but is fine in Eucalyptus). This only occurs when running HyperTable
as the database; MapReduce works fine when HBase is selected.

Note that MapReduce / HyperTable works fine over Eucalyptus.

The problem is that the MapReduce API only talks to Hadoop, not HBase or
HyperTable, so the choice of DB shouldn't matter. Will investigate.

Reproduced with newest image, continuing to investigate.

Verified that this is still a problem with the current code. Will post error 
messages
soon.

Recent code refactoring may have fixed this problem, as it appears to work fine 
now.
The new code changes don't change /etc/hosts as they did before, and the new 
version
of Hadoop used appears to not need the hosts spelled out as it did before.

Will re-open if this is a problem on EC2.
