Subject [jira] [Updated] (CASSANDRA-4570) Minor logging additions
Date Tue, 18 Dec 2012 23:08:12 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-4570?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Joaquin Casares updated CASSANDRA-4570:
---------------------------------------

    Attachment: info_paths_v2.txt
                mt_compaction_v2.txt
                jvm_warnings_v2.txt

jvm_warnings_v2:

Now only checks the 1.6.0 releases. Updated the minor revision numbers to be in line with
what we're currently seeing.

mt_compaction_v2:

Moved this to DatabaseDescriptor where it should be.

info_paths_v2:

Now displaying this shortly after the yaml path is printed.

check_tables (original):

Nope, this only logs once. The issue before was that it was always logging "Found table data
in data directories. Consider using the CQL shell to define your schema."

With the patch: http://aep.appspot.com/display/xITUgvlTOPjfmCnL_ns6tkXhZ1s/
Without: http://aep.appspot.com/display/6ffn0ucc0pCEHS53p6nX9J0sgnM/

Probably due to: Schema.instance.addSystemTable(systemMeta);
being run before loadSchemas().
