Raju Bairishetti commented on LENS-853:
---------------------------------------
bq. Needs more investigation. Setting isConnectionAlive to true during
setClient causes the API to fail during close session.
Tests were failing because it was tying to close singleton lens client
always even though we are creating multliple lens client instances in test
cases. closeSession is throwing "Hive session does not exists" exception when
it is trying to close session from cli test cases.
> Quitting shell(quitshell()) is not closing session some times.

> Quitting session through programmatically is not closing the session some
> times.
> First it checks whether connection to server is active or not to close the
> session. It is depending on isConnectionActive variable to check the
> connection is active or not. Right now we are setting isConnectionActive to
> true only if user calls getClient(). isConnectionActive should be set to
> true when user calls setClient(client).
> code snippets:
> ----------------
> {code}
> public LensClient getClient() {
> if (lensClient == null) {
> setClient(getClientWrapper().getClient());
> isConnectionActive = true;
> }
> return lensClient;
> }
> {code}
> {code}
> protected static synchronized void closeClientConnection() {
> if (isConnectionActive) {
> log.debug("Request for stopping lens cli received");
> getClientWrapper().getClient().closeConnection();
> isConnectionActive = false;
> }
> }
> {code}
