Description
Reproduction
Execute the following command:
//代码占位符 ${HBASE_HOME}/bin/hbase --config /etc/hbase-conf hbck -j ~/hbase-operator-tools/hbase-hbck2/target/hbase-hbck2-1.0.0-SNAPSHOT.jar
we would get IndexOutOfBoundsException, as following.
//代码占位符 Caused by: java.lang.StringIndexOutOfBoundsException: String index out of range: -1 at java.lang.String.substring(String.java:1967) at org.apache.logging.log4j.util.PropertiesUtil.partitionOnCommonPrefixes(PropertiesUtil.java:555) at org.apache.logging.log4j.core.config.properties.PropertiesConfigurationBuilder.build(PropertiesConfigurationBuilder.java:174) at org.apache.logging.log4j.core.config.properties.PropertiesConfigurationFactory.getConfiguration(PropertiesConfigurationFactory.java:56) at org.apache.logging.log4j.core.config.properties.PropertiesConfigurationFactory.getConfiguration(PropertiesConfigurationFactory.java:35) at org.apache.logging.log4j.core.config.ConfigurationFactory$Factory.getConfiguration(ConfigurationFactory.java:557) at org.apache.logging.log4j.core.config.ConfigurationFactory$Factory.getConfiguration(ConfigurationFactory.java:481) at org.apache.logging.log4j.core.config.ConfigurationFactory.getConfiguration(ConfigurationFactory.java:323) at org.apache.logging.log4j.core.LoggerContext.reconfigure(LoggerContext.java:695) at org.apache.logging.log4j.core.LoggerContext.reconfigure(LoggerContext.java:716) at org.apache.logging.log4j.core.LoggerContext.start(LoggerContext.java:270) at org.apache.logging.log4j.core.impl.Log4jContextFactory.getContext(Log4jContextFactory.java:155) at org.apache.logging.log4j.core.impl.Log4jContextFactory.getContext(Log4jContextFactory.java:47) at org.apache.logging.log4j.LogManager.getContext(LogManager.java:196) at org.apache.logging.log4j.spi.AbstractLoggerAdapter.getContext(AbstractLoggerAdapter.java:137) at org.apache.logging.slf4j.Log4jLoggerFactory.getContext(Log4jLoggerFactory.java:55) at org.apache.logging.log4j.spi.AbstractLoggerAdapter.getLogger(AbstractLoggerAdapter.java:47) at org.apache.logging.slf4j.Log4jLoggerFactory.getLogger(Log4jLoggerFactory.java:33) at org.slf4j.LoggerFactory.getLogger(LoggerFactory.java:358) at org.slf4j.LoggerFactory.getLogger(LoggerFactory.java:383) at org.apache.hbase.HBCK2.<clinit>(HBCK2.java:92)
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.
