Subject [jira] [Commented] (CASSANDRA-2497) CLI: issue with keys being interpreted as hex and causing SET statement to fail
Date Mon, 18 Apr 2011 21:54:05 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-2497?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13021294#comment-13021294
] 

Cathy Daw commented on CASSANDRA-2497:
--------------------------------------

Restarting the CLI did not fix the issue.
Adding an assume for the key type did.

{code}
[default@cathy] set users['jsmith']['password']='ch@ngem3';
org.apache.cassandra.db.marshal.MarshalException: cannot parse 'jsmith' as hex bytes

[default@cathy] assume users keys as ascii;
Assumption for column family 'users' added successfully.

[default@cathy] set users['jsmith']['password']='ch@ngem3';
Value inserted.
{code}

> *Original Summary*: Issues with Update Column Family and adding a key_validation_class
> _Changed summary because the issue repros on drop/create.  see comment._
> *Reproduction Steps*
> {code}
> create column family users with comparator = UTF8Type 
> and column_metadata = [{column_name: password, validation_class: UTF8Type}];
> update column family users with key_validation_class=UTF8Type;
> set users['jsmith']['password']='ch@ngem3';          
> {code}
> *EXPECTED RESULT:* After the UPDATE statement, the SET statement should go through successfully.
> *ACTUAL RESULT:*  The SET statement gives the same error message, regardless of the UPDATE
