Raju Bairishetti closed LENS-576. --------------------------------- > Cannot retrieve query results on lens server restart > ---------------------------------------------------- > > Key: LENS-576 > URL: https://issues.apache.org/jira/browse/LENS-576 > Project: Apache Lens > Issue Type: Bug > Reporter: Deepak Barr > Assignee: Deepak Barr > Priority: Critical > Fix For: 2.4 > > Attachments: LENS-576.3.patch > > > In the event of lens server restart, We can not obtain the query result by > calling "/queryuiapi/queries/{queryHandle}/httpresultset" API as > LensPersistentResult does not get created. This is because > QueryOutputFormatter variable in QueryContext object is always null.This > QueryOutputFormatter is important to create LensPersistedResultSet (see > getResultset() method in QueryExecutionServiceImpl class) . > Reason : One can see that QueryOutputFormatter variable in QueryContext class > is not serialized. Therefore, on server restart, this variable is always null > in QueryContext for all queries. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
