Subject [jira] [Updated] (AMBARI-1256) Host registration can fail due to mount point info not fitting ambari.hosts::disks_info column
Date Fri, 25 Jan 2013 02:35:14 GMT

     [ https://issues.apache.org/jira/browse/AMBARI-1256?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Sumit Mohanty updated AMBARI-1256:
----------------------------------

    Attachment: Ambari-upgrade-1256.patch

The SQL file for upgrade includes the version number assuming all upgrade files for multiple
versions are at the same location /var/lib/ambari-server/resources. Other option is to create
version specific directories and drop the similarly named files (this could be confusing as
file names will not capture version info).

Are their any more sanity checks necessary during upgrade (in ambari-server.py file)?

> Currently disks_info column is 2000 characters long.
> For one of the users, this was not big enough to fit all the mount points detected (they
had 40+ mount points on their hosts).
> We made this disks_info column size to be 10000 to workaround this issue.
> Ensure that upgrade supports performing schema alteration on an existing installation.
