multiple columns
[ https://issues.apache.org/jira/browse/HBASE-18999?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16417482#comment-16417482 ]

Based on [ruby documentation|http://ruby-doc.org/core-2.2.2/Hash.html]
{quote}Hashes enumerate their values in the order that the corresponding keys were inserted.
{quote}
So, the key which is inserted first would overwrite the previous one.
For example:
{code:java}
hbase(main):024:0> put 't1', 'row2', {'family1:column1'=>'a value1', 'family1:column1'=>'another value1', 'family2'=>'foobar1'}
Took 0.0020 seconds
hbase(main):025:0> scan 't1'
ROW COLUMN+CELL
row1 column=family1:column1, timestamp=1522249091760, value=a value1
row1 column=family2:, timestamp=1522249091760, value=foobar1
row1 column=family2:column2, timestamp=1522249091760, value=another value1
row2 column=family1:column1, timestamp=1522249109960, value=another value1
row2 column=family2:, timestamp=1522249109960, value=foobar1
2 row(s)
Took 0.0068 seconds
hbase(main):026:0> put 't1', 'row2', {'family2:column2'=>'a value1', 'family2:column2'=>'another value1', 'family2'=>'foobar1'}
Took 0.0042 seconds
hbase(main):027:0> scan 't1'
ROW COLUMN+CELL
row1 column=family1:column1, timestamp=1522249091760, value=a value1
row1 column=family2:, timestamp=1522249091760, value=foobar1
row1 column=family2:column2, timestamp=1522249091760, value=another value1
row2 column=family1:column1, timestamp=1522249109960, value=another value1
