Subject [jira] Commented: (PIG-893) support cast of chararray to other simple types
Date Thu, 06 Aug 2009 18:33:14 GMT

    [ https://issues.apache.org/jira/browse/PIG-893?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12740188#action_12740188
] 

Alan Gates commented on PIG-893:
--------------------------------

CastUtil should not include byteToX() calls.  Pig never casts from ByteArray to a type, it
leaves that to loaders because Pig has no idea what the representation of the data is in the
bytes.  It might be UTF8 (as it is for PigStorage) or something entirely different.

CastUtil.stringToX calls should not call byteToX methods.  This is inefficient since those
methods just turn the bytes back into a String and then do the conversion explicitly.

> Pig should support casting of chararray to integer,long,float,double,bytearray. If the
conversion fails for reasons such as overflow, cast should return null and log a warning.
