--------------------------------------
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.
