Subject [jira] [Commented] (HBASE-5338) Add SKIP support to importtsv
Date Sun, 11 Aug 2013 17:42:48 GMT

    [ https://issues.apache.org/jira/browse/HBASE-5338?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13736355#comment-13736355
] 

Harsh J commented on HBASE-5338:
--------------------------------

@Lars - I preferred to implement a missing value skipper instead. That is 'a,,c,d' is valid
in meaning that 'b' (non-existent in the spec) will get skipped. Works at ends too.

> It'd be nice to have support for "SKIP" mappings so that you can omit columns from the
TSV during the import. For example
> {code}
> -Dimporttsv.columns=SKIP,HBASE_ROW_KEY,cf1:col1,cf1:col2,SKIP,SKIP,cf2:col1...
> {code}
> Or maybe HBASE_SKIP_COLUMN to be less ambiguous.
