[jira] [Commented] (HBASE-19245) MultiTableInputFormatBase#getSplits creates a Connection per Table

    [ https://issues.apache.org/jira/browse/HBASE-19245?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16250078#comment-16250078 ] 

stack commented on HBASE-19245:
-------------------------------

.001 Move the Connection setup earlier in the function (involves a right-shift of method interior so it looks like a bigger change than it is).

> Doesn't have to. Connection setup costs. Shared Connection could save on hbase:meta hits (perhaps).
