The "GettingStarted" page has been changed by MakiWatanabe: http://wiki.apache.org/cassandra/GettingStarted?action=diff&rev1=63&rev2=64 Comment: Add a note for update limitation on comparators (CASSANDRA-2809) Please note that we didn't use "utf8()" for the row key this time. You can define the data type as meta data of the column family. Check 'help update column family;' and 'help create column family;' for more details. + Note: You can't update comparator (validation class for "column name") after creating column family. Please refer to [[https://issues.apache.org/jira/browse/CASSANDRA-2809?focusedCommentId=13053420&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-13053420|CASSANDRA-2809]]. + To be certain though, take some time to try out the examples in CassandraCli before moving on Also, if you run into problems, Don't Panic, calmly proceed to [[#if_something_goes_wrong|If Something Goes Wrong]].
