This sounds similar to a previous email chain from a few months ago. I
think your answer may be in there.

Subject:	Globally Unique/ User defined session Ids


Is there support for sessionId to be GUID for batch usecase ? or can the
sessionId be made to be user-defined.

This will be useful for uniquely identifying sessions across restarts or
crashes. We are maintaining client side mappings to session Id and
restart / HA scenarios will make this session Id irrelevant.

Found this Jira ticket , but no
further comments on it.

It would be good if there is an option to assign GUID for a session,
similar to Yarn AppId, which will be unique for certain extent.

Please suggest what is the best way to maintain sessionIds across restarts
or HA scenarios ?
