Subject [jira] [Commented] (HBASE-7156) Add Data Block Encoding and -D opts to Performance Evaluation
Date Tue, 13 Nov 2012 21:36:13 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7156?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13496571#comment-13496571

Matteo Bertozzi commented on HBASE-7156:

{quote}The space after '-D' should be removed, right?{quote}

both syntax are valid... -D property=value or -Dproperty=value
if you look at the Export tool the help is mixed with space and not.
I find the space one much cleaner to read, but if we go for the non space one as default I'm
ok with it.
