jiang he commented on HBASE-30248:
----------------------------------
I tried to assign this issue to mazhengxuan, but it looks like the user is not
assignable in the HBASE project yet. Could someone with JIRA project
permission please assign HBASE-30248 to mazhengxuan, or add them as an
assignable user? In the meantime, I am fine with mazhengxuan working on this
issue, and I can help verify the patch with the original reproducer once a PR
is available.
> Negative hbase.snapshot.region.timeout causes RegionServer abort during
> snapshot procedure initialization
> ---------------------------------------------------------------------------------------------------------
>
> Key: HBASE-30248
> URL: https://issues.apache.org/jira/browse/HBASE-30248
> Project: HBase
> Issue Type: Bug
> Components: regionserver
> Affects Versions: 2.5.14
> Environment: ## Environment
> - HBase version: 2.5.14
> - Java: OpenJDK 11
> - Mode: local standalone HBase
> - OS: Linux / WSL2
>
> Reporter: jiang he
> Priority: Major
>
> When `hbase.snapshot.region.timeout` is configured as a negative value, the
> RegionServer aborts during initialization.
> The negative value is passed as the keep-alive time to a
> `ThreadPoolExecutor`, which throws `IllegalArgumentException`.
> ## Reproducer
> Use the following `hbase-site.xml` entries:
> ```xml
> <configuration>
> <property>
> <name>hbase.rootdir</name>
> <value>/tmp/hbase-tmp</value>
> </property>
> <property>
> <name>hbase.cluster.distributed</name>
> <value>false</value>
> </property>
> <property>
> <name>hbase.unsafe.stream.capability.enforce</name>
> <value>false</value>
> </property>
> <property>
> <name>hbase.snapshot.region.timeout</name>
> <value>-300000</value>
> </property>
> </configuration>
> Then start HBase.
> Actual result
> The RegionServer aborts:
> ERROR [RS:0;...] regionserver.HRegionServer:
> ***** ABORTING region server ... Initialization of RS failed. Hence
> aborting RS. *****
> java.lang.IllegalArgumentException
> at
> java.base/java.util.concurrent.ThreadPoolExecutor.<init>(ThreadPoolExecutor.java:1293)
> at
> java.base/java.util.concurrent.ThreadPoolExecutor.<init>(ThreadPoolExecutor.java:1215)
> at
> org.apache.hadoop.hbase.procedure.ProcedureMember.defaultPool(ProcedureMember.java:86)
> at
> org.apache.hadoop.hbase.regionserver.snapshot.RegionServerSnapshotManager.initialize(RegionServerSnapshotManager.j
> ava:391)
> Root cause
> hbase.snapshot.region.timeout is read in
> RegionServerSnapshotManager.initialize and used as the keep-alive time when
> creating the snapshot procedure member thread pool.
> A negative value is invalid for ThreadPoolExecutor.
> Expected result
> HBase should validate hbase.snapshot.region.timeout and reject negative
> values with a clear configuration error, or fall
> back to a safe default.
> The RegionServer should not abort with a raw IllegalArgumentException.
> Notes
> The failure was found by configuration fuzzing.
