Subject [jira] [Commented] (IGNITE-2155) CacheStarSchemaExample isn't clear and it seems the output is wrong
Date Tue, 15 Dec 2015 13:57:46 GMT

    [ https://issues.apache.org/jira/browse/IGNITE-2155?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15058079#comment-15058079
] 

Ilya Suntsov commented on IGNITE-2155:
--------------------------------------

For 
{noformat}examples/src/main/java/org/apache/ignite/examples/datagrid/starschema/CacheStarSchemaExample.java
{noformat}
fix confirmed but I observerd the same behavior for:
{noformat}examples/src/main/scala/org/apache/ignite/scalar/examples/ScalarSnowflakeSchemaExample.scala{noformat}
