Subject [jira] Commented: (PIG-1468) DataByteArray.compareTo() does not compare in lexicographic order
Date Fri, 09 Jul 2010 18:41:52 GMT

    [ https://issues.apache.org/jira/browse/PIG-1468?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12886819#action_12886819
] 

Daniel Dai commented on PIG-1468:
---------------------------------

The other concern is we only change DataByteArray not byte. So comparator for DataType.BYTEARRAY
and DataType.BYTE is different. This will cause confusion.

> The compareTo() method of org.apache.pig.data.DataByteArray does not compare items in
lexicographic order.
> Actually, it takes into account the signum of the bytes that compose the DataByteArray.
> So, for example, 0xff compares to less than 0x00
