Subject [jira] [Commented] (HBASE-14406) The dataframe datasource filter is wrong, and will result in data loss or unexpected behavior
Date Mon, 12 Oct 2015 16:59:05 GMT

    [ https://issues.apache.org/jira/browse/HBASE-14406?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14953360#comment-14953360
] 

Ted Malaska commented on HBASE-14406:
-------------------------------------

I think the bug from last time was the following two

( rowkey < 1 or col > 2 )

and

( colA < 1 or colB > 2 )

The functionality of (rowkey < 1 and col > 2) worked in the last patch

But here are some related tests that should cover both cases
test("Test SQL point and range combo") 
test("Test OR logic with a one RowKey and One column")
test("Test two complete range non merge rowKey query")
test("Test OR logic with a two columns")
