Subject [jira] [Commented] (HBASE-7414) Convert some HFile metadata to PB
Date Sat, 05 Jan 2013 03:20:12 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7414?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13544553#comment-13544553
] 

Ted Yu commented on HBASE-7414:
-------------------------------

Looking at HFileBlock.java:
{code}
  static final int MINOR_VERSION_WITH_CHECKSUM = 1;
  static final int MINOR_VERSION_NO_CHECKSUM = 0;
{code}
It seems that MINOR_VERSION of 2 doesn't correspond to a particular feature. 2 is just marked
as MAX_MINOR_VERSION.
So I guess PBUF_TRAILER_MINOR_VERSION can carry value of 2.

It would be nice if MINOR_VERSION constants can be found in one place so that it is easier
to maintain.

> Convertion should be in a manner that does not prevent our being able to read old style
hfiles with Writable metadata.
