Tianying Chang updated HBASE-17453: ----------------------------------- Attachment: (was: HBASE-17453-master.patch) > add Ping into HBase server for deprecated GetProtocolVersion > ------------------------------------------------------------ > > Key: HBASE-17453 > URL: https://issues.apache.org/jira/browse/HBASE-17453 > Project: HBase > Issue Type: Improvement > Components: regionserver > Affects Versions: 1.2.2 > Reporter: Tianying Chang > Assignee: Tianying Chang > Priority: Minor > Attachments: HBASE-17453-1.2.patch > > > Our HBase service is hosted in AWS. We saw cases where the connection between > the client (Asynchbase in our case) and server stop working but did not throw > any exception, therefore traffic stuck. So we added a "Ping" feature in > AsyncHBase 1.5 by utilizing the GetProtocolVersion() API provided at RS side, > if no traffic for given time, we send the "Ping", if no response back for > "Ping", we assume the connect is bad and reconnect. > Now we are upgrading cluster from 94 to 1.2. However, GetProtocolVersion() is > deprecated. To be able to support same detect/reconnect feature, we added > Ping() in our internal HBase 1.2 branch, and also patched accordingly in > Asynchbase 1.7. > We would like to open source this feature since it is useful for use case in > AWS environment. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
