Chia-Ping Tsai updated HBASE-17887: ----------------------------------- Attachment: HBASE-17887.branch-1.v3.patch Both of the cell set and time tracker are necessary for MemStoreScanner in branch-1, so we need to copy the references of them atomically. Otherwise, the wrong time tracker may make the MemStoreScanner be skipped(see MemStoreScanner#shouldSeek). I don't want to use the lock/sync, hence I create an new inner class in MemStoreScanner to contain those fields. The v3.patch introduces more changes than v2.patch. [~ram_krish] I add the test TestStore#testScanWithDoubleFlush. Would you please take a look? > TestAcidGuarantees fails frequently > ----------------------------------- > > Key: HBASE-17887 > URL: https://issues.apache.org/jira/browse/HBASE-17887 > Project: HBase > Issue Type: Bug > Components: regionserver > Affects Versions: 2.0.0 > Reporter: Umesh Agashe > Assignee: Chia-Ping Tsai > Priority: Blocker > Fix For: 2.0.0, 1.4.0, 1.2.6, 1.3.2, 1.4.1 > > Attachments: HBASE-17887.branch-1.v0.patch, > HBASE-17887.branch-1.v1.patch, HBASE-17887.branch-1.v1.patch, > HBASE-17887.branch-1.v2.patch, HBASE-17887.branch-1.v2.patch, > HBASE-17887.branch-1.v3.patch, HBASE-17887.v0.patch, HBASE-17887.v1.patch > > > As per the flaky tests dashboard here: > https://builds.apache.org/job/HBASE-Find-Flaky-Tests/lastSuccessfulBuild/artifact/dashboard.html, > It fails 30% of the time. > While working on HBASE-17863, a few verification builds on patch failed due > to TestAcidGuarantees didn't pass. IMHO, the changes for HBASE-17863 are > unlikely to affect get/ put path. > I ran the test with and without the patch several times locally and found > that TestAcidGuarantees fails without the patch similar number of times. > Opening blocker, considering acid guarantees are critical to HBase. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
