[jira] [Commented] (HBASE-7170) [0.94 branch] Allow
HConnectionImplementation to reconnect to master multiple times
[ https://issues.apache.org/jira/browse/HBASE-7170?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13498427#comment-13498427 ]
Gregory Chanan commented on HBASE-7170:
---------------------------------------
Two notes:
- the last sentence should be "all the tests that are executed after testUnmanagedHConnectionReconnect fail [without the changes to HConnectionImplementation]"
- Trunk doesn't have this issue.

> HBASE-5058 retained the old behavior of managed HConnections not retrying their connection to master b/c of the "masterChecked" variable.
> This behavior isn't great though, because you can get in the following situation:
> 1) Connect to master using HBaseAdmin
> 2) Master goes down
> 3) New master takes over
> 4) The HBaseAdmin object is now useless
> The client needs to create a new HBaseAdmin in this case.
