kangkaisen commented on KYLIN-1992: ----------------------------------- Thanks for your comment. Firstly, this minor issue could be reproduced stably. we could make a continuous and successful query go through while loop, in the meantime,we could make a failed query with syntax error . In this way, we will get wrong `Realization Names` in the failed query log and the `Realization Names` belong to the successful query. Secondly, most of failed query had this issue failed because the sql parsed wrong and didn't start to scan HBase. Thirdly, I am sorry for I did't consider the integration query tests. > Clear ThreadLocal Contexts when query failed before scaning HBase > ----------------------------------------------------------------- > > Key: KYLIN-1992 > URL: https://issues.apache.org/jira/browse/KYLIN-1992 > Project: Kylin > Issue Type: Bug > Reporter: kangkaisen > Assignee: kangkaisen > Priority: Minor > Attachments: KYLIN-1992.patch > > > currently, we call `OLAPContext.clearThreadLocalContexts()` function before > scaning HBase. > if query failed before scaning HBase, we would get wrong `realization` of the > query in the log possibly. > Because the thread pool of Tomcat multiplexed the thread and didn't clear > ThreadLocal variable. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
