Subject [jira] Commented: (HBASE-532) Odd interaction between HRegion.get, HRegion.deleteAll and compactions
Date Tue, 15 Apr 2008 03:07:04 GMT

    [ https://issues.apache.org/jira/browse/HBASE-532?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12588883#action_12588883
] 

stack commented on HBASE-532:
-----------------------------

Now I remember.  getNextRow does not suppress deletes because perhaps client is interested
in deletes.  In scanner case, next calls getNextRow, then does a getFull.  If row only has
deletes, next calls getFull again till it gets a row with content.  I can improve the method
comment before I commit -- unless you have other things you'd like me fix?

Thanks for the review.

> If you apply the patch for HBASE-483 to the 0.1 branch and comment out lines 309 and
315 of MetaUtils.java (which force compactions of the root and meta regions respectively),
TestMergeTool fails. Why forcing compactions makes the test succeed is a mystery to me.
