Date Sat, 17 Dec 2016 01:13:58 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15432?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15755980#comment-15755980

Xuesen Liang commented on HBASE-15432:

Yes, the space is intentional. It's for testing that if user write whitespace, it still work

Both "=a,   b" and "=a,b" are fine.

> Currently Hbase TableInputFormat class has SCAN_COLUMN_FAMILY and SCAN_COLUMNS. SCAN_COLUMN_FAMILY
can only scan single column family. If we need to scan multiple column families from a table
then we must use SCAN_COLUMNS where we must provide both columns and column families which
is not a convenient. Can we have a SCAN_COLUMN_FAMILIES which supports scan of multiple column
