> OfflineMetaRepair tool may cause HMaster abort always
> -----------------------------------------------------
>
> Key: HBASE-18167
> URL: https://issues.apache.org/jira/browse/HBASE-18167
> Project: HBase
> Issue Type: Bug
> Components: master
> Affects Versions: 1.4.0, 1.3.1, 1.3.2
> Reporter: Pankaj Kumar
> Assignee: Pankaj Kumar
> Priority: Critical
> Fix For: 1.4.0, 1.3.2
>
> Attachments: HBASE-18167.branch-1.3.V2.patch,
> HBASE-18167-branch-1.patch, HBASE-18167-branch-1-V2.patch
>
>
> In the production environment, we met a weird scenario where some Meta table
> HFile blocks were missing due to some reason.
> To recover the environment we tried to rebuild the meta using
> OfflineMetaRepair tool and restart the cluster, but HMaster couldn't finish
> it's initialization. It always timed out as namespace table region was never
> assigned.
> Steps to reproduce
> ==================
> 1. Assign meta table region to HMaster (it can be on any RS, just to
> reproduce the scenario)
> {noformat}
> <property>
> <name>hbase.balancer.tablesOnMaster</name>
> <value>hbase:meta</value>
> </property>
> {noformat}
> 2. Start HMaster and RegionServer
> 2. Create two namespace, say "ns1" & "ns2"
> 3. Create two tables "ns1:t1' & "ns2:t1'
> 4. flush 'hbase:meta"
> 5. Stop HMaster (graceful shutdown)
> 6. Kill -9 RegionServer (Abnormal shutdown)
> 7. Run OfflineMetaRepair as follows,
> {noformat}
> hbase org.apache.hadoop.hbase.util.hbck.OfflineMetaRepair -fix
> {noformat}
> 8. Restart HMaster and RegionServer
> 9. HMaster will never be able to finish its initialization and abort always
> with below message,
> {code}
> 2017-06-06 15:11:07,582 FATAL [Hostname:16000.activeMasterManager]
> master.HMaster: Unhandled exception. Starting shutdown.
> java.io.IOException: Timedout 120000ms waiting for namespace table to be
> assigned
> at
> org.apache.hadoop.hbase.master.TableNamespaceManager.start(TableNamespaceManager.java:98)
> at
> org.apache.hadoop.hbase.master.HMaster.initNamespace(HMaster.java:1054)
> at
> org.apache.hadoop.hbase.master.HMaster.finishActiveMasterInitialization(HMaster.java:848)
> at org.apache.hadoop.hbase.master.HMaster.access$600(HMaster.java:199)
> at org.apache.hadoop.hbase.master.HMaster$2.run(HMaster.java:1871)
> at java.lang.Thread.run(Thread.java:745)
> {code}
> Root cause
> ==========
> 1. During HM start up AM assumes that it's a failover scenario based on the
> existing old WAL files, so SSH/SCP will split WAL files and assign the
> holding regions.
> 2. During SSH/SCP it retrieves the server holding regions from meta/AM's
> in-memory-state, but meta only had "regioninfo" entry (as already rebuild by
> OfflineMetaRepair). So empty region will be returned and it wont trigger any
> assignment.
> 3. HMaster which is waiting for namespace table to be assigned will timeout
> and abort always.
