> Key: HBASE-29586
> URL: https://issues.apache.org/jira/browse/HBASE-29586
> Project: HBase
> Issue Type: Bug
> Reporter: wangxiangdong
> Assignee: wangxiangdong
> Priority: Minor
> Labels: pull-request-available
> Fix For: 2.7.0, 3.0.0-beta-2, 2.6.5, 2.5.14
>
>
> [problem]
> HBase Master will be initialized with the following setting:
> <property>
> <name>hbase.oldwals.cleaner.thread.size</name>
> <value>-1</value>
> <description>Default is 2</description>
> </property>
> After we read the source code, we found that
> "hbase.oldwals.cleaner.thread.size" is parsed and used in
> onConfigurationChange() function without checking:
> {code:java}
> int newSize = conf.getInt(OLD_WALS_CLEANER_THREAD_SIZE,
> DEFAULT_OLD_WALS_CLEANER_THREAD_SIZE);
> if (newSize == oldWALsCleaner.size()) {
> LOG.debug( "Size from configuration is the same as previous which " +
> "is {}, no need to update.", newSize); return;
> }
> interruptOldWALsCleaner();
> oldWALsCleaner = createOldWalsCleaner(newSize);{code}
> The value of "hbase.oldwals.cleaner.thread.size" will be served as the
> initialCapacity of ArrayList. If the configuration value is negative, an
> IllegalArgumentException will be thrown.:
> {code:java}
> private List<Thread> createOldWalsCleaner(int size) {
> ...
> List<Thread> oldWALsCleaner = new ArrayList<>(size);
> ...
> } {code}
