[jira] [Created] (CASSANDRA-4582) in cqlsh the output of describe
columnfamily doesn't convert to hex
Jeremy Hanna created CASSANDRA-4582:
---------------------------------------
Summary: in cqlsh the output of describe columnfamily doesn't convert to hex
Key: CASSANDRA-4582
URL: https://issues.apache.org/jira/browse/CASSANDRA-4582
Project: Cassandra
Issue Type: Bug
Reporter: Jeremy Hanna
Priority: Minor
When the comparator=blob, cqlsh is outputting the metadata for column names in utf8. Instead it should output them in hex because that's what will make it so its output can be used to re-create the column family. Granted it's going to be pretty unreadable for the user, but it will work to re-create the CF.

Yeah. If it's that much work then don't worry about it. Sounds like it's already addressed in a newer version.

----------------------------------------
It's not. But the whole problem doesn't exist in cql3 (all column names are utf8 there).

[jira] [Resolved] (CASSANDRA-4582) in cqlsh the output of describe
columnfamily doesn't convert to hex
Posted by "paul cannon (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/CASSANDRA-4582?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
paul cannon resolved CASSANDRA-4582.
------------------------------------
Resolution: Won't Fix
I'd like to implement this fix, but it's a little less trivial than it sounds to do this in a general way for all comparator classes- cqlsh needs to decode the binary column names according to the comparator class (easy), and then translate the native python values back into a textual format that CQL will parse correctly for a value of the original class (not as easy).
The machinery to do that sort of thing is in the trunk (1.2) branch, but it's not in 1.1, and since this only applies to certain cql2 cases, it doesn't seem like it would be as useful to put only in cassandra 1.2. Affecting the usefulness even further is the fact that it seems to be rare to put explicit column names in a cfdef's column_metadata when the column names use a non-textual comparator type (where one usually uses wide rows, not pre-defined columns).
I could backport the more powerful translation machinery to 1.1, but it would aggravate the already-somewhat-hairy merging situation for cqlsh.
We could also just make this change for comparator=blob and not for the others, but it doesn't seem clear to me that this would be any more useful for blob than, say, timeuuid or float or whatever.
Therefore, I'll close this ticket for now; if anyone still feels strongly about the need and has more convincing input on use cases, we can open it back up.
