Hudson commented on HBASE-1212: ------------------------------- FAILURE: Integrated in HBase-0.94-security #306 (See [https://builds.apache.org/job/HBase-0.94-security/306/]) HBASE-9504 Backport HBASE-1212 to 0.94 - merge tool expects regions all have different sequence ids (Jean-Marc Spaggiari) (larsh: rev 1528280) * /hbase/branches/0.94/src/main/java/org/apache/hadoop/hbase/regionserver/HRegion.java > merge tool expects regions all have different sequence ids > ---------------------------------------------------------- > > Key: HBASE-1212 > URL: https://issues.apache.org/jira/browse/HBASE-1212 > Project: HBase > Issue Type: Bug > Reporter: stack > Assignee: Jean-Marc Spaggiari > Fix For: 0.95.1 > > Attachments: failure.log, HBASE-1212.patch, HBASE-1212-v2.patch, > HBASE-1212-v3-trunk.patch > > > Currently merging two regions, the merge tool will compare their sequence > ids. If same, it will decrement one. It needs to do this because on region > open, files are keyed by their sequenceid; if two the same, one will erase > the other. > Well, with the move to the aggregating hfile format, the sequenceid is > written when the file is created and its no longer written into an aside file > but as metadata on to the end of the file. Changing the sequenceid is no > longer an option. > This issue is about figuring a solution for the rare case where two store > files have same sequence id AND we want to merge the two regions. -- This message was sent by Atlassian JIRA (v6.1#6144)
