Subject [jira] [Commented] (HBASE-12889) Add scanner caching and batching options for the CopyTable job.
Date Fri, 23 Jan 2015 19:03:35 GMT

    [ https://issues.apache.org/jira/browse/HBASE-12889?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14289745#comment-14289745

Nick Dimiduk commented on HBASE-12889:

Our command line tools are a little schizophrenic. Have a look at TableInputFormat: all of
these things are configurable IF no scan object is provided. IMHO, it would be better if we
could expose this basic functionality across the board. I opened a ticket a while back to
clean all this up, HBASE-8074. That's my preference over adding up a bunch of option flags
on each tool, one by one.

> We use the copy table job to ship data between clusters.  Sometimes we have very wide
rows and it is nice to be able to set the batching and caching.  I'll attach trivial patches
for you guys.
