> heartbeatExecutorService was made to be a global to avoid ...
Small clarification: the service was already global (static), this didn't
change in HIVE-24179.
The service seems to be directly related with the lifecycle of the
DbTxnManager so it could be a good idea to make it instance based. This PR
addresses another problem so we could continue this discussion (instance vs
class variable) if necessary in a separate JIRA.
