--------------------------------------------
Summary: Fix 2.0 key and column aliases serialization and cqlsh
DESC SCHEMA
Key: CASSANDRA-5489
URL: https://issues.apache.org/jira/browse/CASSANDRA-5489
Project: Cassandra
Issue Type: Bug
Components: Core, Tools
Affects Versions: 2.0
Reporter: Aleksey Yeschenko
Assignee: Aleksey Yeschenko
Priority: Minor
Fix For: 2.0
CASSANDRA-5125 made a slight change to how key_aliases and column_aliases are
serialized in schema. Prior to that we never kept nulls in the the json
pseudo-lists. This does break cqlsh and probably breaks 1.2 nodes receiving
such migrations as well. The patch reverts this behavior and also slightly
modifies cqlsh itself to ignore non-regular columns from system.schema_columns
table.
This patch breaks nothing, since 2.0 already handles 1.2 non-null padded alias
lists.
