If there is no cell has been read, it will be an empty > response. > However, ClientScanner only handles the situation that the client gets an > empty heartbeat and its cache is not empty. If the cache is empty too, it > will be regarded as end-of-region and open a new scanner for next region. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
