             Summary: After migrating from one cluster to another, new hmaster dies when reaching
out to old nodes
                 Key: HBASE-6343
                 URL: https://issues.apache.org/jira/browse/HBASE-6343
             Project: HBase
          Issue Type: Bug
          Components: migration
    Affects Versions: 0.90.6
         Environment: centos 6.0
            Reporter: Patrick


I am migrating from cluster (movetest-a.domain.com to another (movetest-b.domain.com), both
at the same version of hdfs/hbase. I am using mozilla's Backup tool to copy the /hbase files,
but I imagine any copy tool would have this issue. Each cluster has its own zookeeper &
HDFS.

After copying the files, I try to start the new hmaster (movetest-b), and it dies because
it cannot resolve the data nodes from the source cluster (eg data01.movetest-a.domain.com).

Log: http://pastie.org/4212244

Things I tried that did not work:
- delete -ROOT- from the copied data
- delete .META. from the copied data
- cleanly shutdown the source before copying (to flush to disk)

Things I tried that did work:
- add the source nodes to /etc/hosts, pointing at 127.0.0.2 (which give connection refused):
127.0.0.2 data01.movetest-a.domain.com data02.movetest-a.domain.com data03.movetest-a.domain.com

After bringing up the new cluster (with /etc/hosts in place), I was able to delete the /etc/hosts
entries, and bounce hbase without error.
