Rajat Khandelwal created LENS-1418: -------------------------------------- Summary: LensClient is not thread safe Key: LENS-1418 URL: https://issues.apache.org/jira/browse/LENS-1418 Project: Apache Lens Issue Type: Bug Components: client Reporter: Rajat Khandelwal Assignee: Rajat Khandelwal
Using one lens client to fire two queries in two threads results in discrepencies. LensClient has a {{Map<QueryHandle, LensStatement>}} and also has a cached instance of {{LensStatement}}. When two threads fire queries, both use the same statement object. {{LensStatement}} object in turn caches {{LensQuery}} Object. So whichever thread fired query last is the last one to set lens query inside statement causing {{LensClient.getStatement().getQuery()}} to return that query object for all threads. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
