Subject [jira] [Commented] (HADOOP-8825) Reinstate constructors in SequenceFile.BlockCompressWriter and SequenceFile.RecordCompressWriter for compatibility with Hadoop 1
Date Wed, 19 Sep 2012 15:12:07 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8825?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13458742#comment-13458742
] 

Robert Joseph Evans commented on HADOOP-8825:
---------------------------------------------

Just out of curiosity how is Avro accessing these classes?  They are package private classes,
and even though SequenceFile is @Public and @Stable being package private seems to indicate
to me that they are not intended for general consumption.  If Avro is going to use them could
we please mark them @LimitedPrivate for Avro, and perhaps even open them up more so they are
public instead.  So Avro does not have to put their classes in an org.apache.hadoop.io package
to use them.

to support Hadoop 1 and Hadoop 2. See AVRO-1170.
