Ted Yu commented on HBASE-10845: -------------------------------- I started with adding test in TestHRegion by setting up a custom RegionObserver: {code} + conf.set(CoprocessorHost.REGION_COPROCESSOR_CONF_KEY, + BuggyRegionObserver.class.getName()); {code} However the RegionObserver methods weren't called - RegionCoprocessorHost doesn't come into play in the context of TestHRegion. Let me take a look at TestCoprocessorInterface which Lars mentioned. > Memstore snapshot size isn't updated in DefaultMemStore#rollback() > ------------------------------------------------------------------ > > Key: HBASE-10845 > URL: https://issues.apache.org/jira/browse/HBASE-10845 > Project: HBase > Issue Type: Bug > Reporter: Ted Yu > Assignee: Ted Yu > Fix For: 0.99.0, 0.94.19, 0.98.2, 0.96.3 > > Attachments: 10845-v1.txt, 10845-v2.txt > > > In DefaultMemStore#rollback() : > {code} > if (found != null && found.getMvccVersion() == kv.getMvccVersion()) { > this.snapshot.remove(kv); > } > {code} > this.snapshotSize should be updated in case of rollback. -- This message was sent by Atlassian JIRA (v6.2#6252)
