Subject [jira] Commented: (HBASE-532) Odd interaction between HRegion.get, HRegion.deleteAll and compactions
Date Sun, 23 Mar 2008 03:13:24 GMT

    [ https://issues.apache.org/jira/browse/HBASE-532?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12581322#action_12581322
] 

Bryan Duxbury commented on HBASE-532:
-------------------------------------

Forcing a compaction causes multiple mapfiles to unite, resolving any possible issues with
the way get or getFull presume the data to be organized. That is likely the source of the
issue.

> 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.
