---------------------------------

             Summary: 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


currently, we call `OLAPContext.clearThreadLocalContexts()` function before scaning HBase.
if query failed before scaning HBase, we would get wrong `realization` of the query possibly.
Because the thread pool of Tomcat multiplexed the thread and didn't clear ThreadLocal variable.
