stack commented on HADOOP-2668: ------------------------------- I tried to do a migrate and it looks like the below: {code} durruti:~/Documents/checkouts/hadoop-commit/src/contrib/hbase stack$ ./bin/hbase org.apache.hadoop.hbase.util.Migrate 08/01/19 23:05:21 INFO ipc.Client: Retrying connect to server: localhost/127.0.0.1:60000.

Can we make the message better? Looking at the FS, I see the version file and figure that rerunning the start, it'd probably work for me (running the logs).. but it just fails again telling me to migrate. > [hbase] Documentation and improved logging so fact that hbase now requires > migration comes as less of a surprise > ---------------------------------------------------------------------------------------------------------------- > > Key: HADOOP-2668 > URL: https://issues.apache.org/jira/browse/HADOOP-2668 > Project: Hadoop > Issue Type: Bug > Components: contrib/hbase > Reporter: stack > Assignee: stack > Priority: Blocker > Fix For: 0.16.0 > > Attachments: migrate.patch > > > Hbase now checks for a version file.
