Subject [jira] [Commented] (ACCUMULO-1757) Create BatchDeleter with a provided BatchWriter instead of creating a new one
Date Wed, 09 Oct 2013 21:28:42 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-1757?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13790878#comment-13790878

John Vines commented on ACCUMULO-1757:
--------------------------------------

For the tablet location, yes, that's cached in the Instance. But I'm pretty sure the buffer
for writing it unique to the BatchWriter. Otherwise you could get extremely erratic behavior
with multiple BatchWriters.

> For the BatchDeleter, you pass it all the configs you need to create both a Scanner and
a BatchWriter for it to provide really convenient deletes. However, if a client already has
a BatchWriter, it would be convenient to just hand it an existing BatchWriter to use instead
of creating a separate one.
