-------------------------------
Summary: Creating batch sessions seems to be synchronous. Is there
any plan to make it asynchronous ?
Key: LIVY-454
URL: https://issues.apache.org/jira/browse/LIVY-454
Project: Livy
Issue Type: Question
Components: Batch, Server
Affects Versions: 0.5.0, 0.4.0
Reporter: kondziolka
Creating batch sessions seems to be synchronous, below one line from
_BatchSession.scala_ which is executed during creating batch session request.
{code:java}
sessionStore.save(BatchSession.RECOVERY_SESSION_TYPE, s.recoveryMetadata){code}
In case of session storage basing on HDFS, time of creating batch session (so
waiting for answer from server) can be quite long, for example during failover
of some node in Hadoop cluster. It can lead to some integration issues.
Therefore, the question is are you going to provide asynchronous approach to
creating batch session ?
