When the server that we used to have a connection dies and comes back, we have to handle two things: - Clean up all the outgoing RPCs, and set them with exceptions so that the upper layer can retry. - If the server comes back online, we should be able to reconnect to the server by re-creating the pipeline. > [C++] Rpc connection close and reconnecting > ------------------------------------------- > > Key: HBASE-18204 > URL: https://issues.apache.org/jira/browse/HBASE-18204 > Project: HBase > Issue Type: Sub-task > Reporter: Enis Soztutar > Assignee: Enis Soztutar > Attachments: hbase-18204_v1.patch > > > Our client-dispatcher maintains a map of outgoing RPCs per server with the promises. > In case the server goes down, or TCP connection is closed, we should complete the outgoing RPCs with exceptions so that higher level waiters can unblock and retry. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
