Nikita Pande commented on HBASE-28531:
--------------------------------------
[~guluo] I was just in a process of bumping up log4j for hbase-operator tools
from log4j1.x which is being used in hbase-table-reporter. I can take this up
as part of the same or as part of this Jira as well.

> Reproduction
>
> Execute the following command:
> {code:java}

> ~/hbase-operator-tools/hbase-hbck2/target/hbase-hbck2-1.0.0-SNAPSHOT.jar

> The Reason.
> The current version of HBase uses version 2.17.2 of log4j2, which supports
> shorthand syntax for properties configuration ( LOG4J2-3341 :
> https://issues.apache.org/jira/browse/LOG4J2-3341).
>
> However, The current version of HBCK2 uses version 2.17.1 of log4j2, which
> does not support the feature.
> So, we would get IndexOutOfBoundsException when HBCK2 uses as following
> log4j2 properties, and this is the default log configuration format for HBase
> logger.http = INFO,NullAppender
> In order to avoid this problem, I think we need bump log4j2 from 2.17.1 to
> 2.17.2 against HBCK2.
