Subject [jira] [Commented] (AMBARI-1867) Processing API requests takes too long
Date Wed, 10 Apr 2013 22:29:16 GMT

    [ https://issues.apache.org/jira/browse/AMBARI-1867?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13628367#comment-13628367
] 

Sumit Mohanty commented on AMBARI-1867:
---------------------------------------

* ambari-server/src/main/java/org/apache/ambari/server/orm/dao/StageDAO.java 
** Are we expected to wrap even single statement with { }? If so then lines 118/131/133 should
be enclosed with { }
** findRequestContext - perhaps its OK. When we send invalid request id then we will still
get empty string
* ambari-server/src/main/java/org/apache/ambari/server/controller/AmbariManagementControllerImpl.java
(
** Line 3591: Why is this method decorated Transactional? Should it be @Transactional(readOnly
= True)?
* ambari-server/src/main/java/org/apache/ambari/server/orm/dao/DaoUtils.java 
** Whats the difference between selectOne and selectSingle?
