[jira] [Commented] (CASSANDRA-18058) In-memory index and query path
[ https://issues.apache.org/jira/browse/CASSANDRA-18058?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17638653#comment-17638653 ]
Andres de la Peña commented on CASSANDRA-18058:
-----------------------------------------------
It seems that there is a build error due to {{checkstyle}} detecting some unused imports:
{code:java}
checkstyle:

{code}
That prevents us from running the patch on CI, that uses {{checkstyle}} on the root build jobs.
