Summary: Logging Enhancement on Configuration Setting in
RpcConnection
Key: HBASE-28818
URL: https://issues.apache.org/jira/browse/HBASE-28818
Project: HBase
Issue Type: Improvement
Components: Client
Affects Versions: 3.0.0-beta-1
Environment: Version: 3.0.0-beta-1
Location:
{{`hbase/hbase-client/src/main/java/org/apache/hadoop/hbase/ipc/RpcConnection.java`}}
in method {{{}`{}}}{*}{{getConnectionHeader}}{*}{{{}`{}}}. Lines 218-223.
Reporter: LoggingResearch
Attachments: TestNettyRpcConnection.java, original-vs-log-enhanced.md
The original implementation of the {{getConnectionHeader()}} method in
{{RpcConnection}} does not include detailed logging regarding the configuration
of the Crypto AES feature. This lack of logging can lead to several issues: #
*Undetected Crypto AES Configuration:* If Crypto AES is enabled or disabled
without proper logging, administrators may not be aware of the active
encryption settings. This can lead to a misconfigured environment where
sensitive data is not properly secured, or unnecessary resources are consumed
by enabling encryption when it's not required.
#
*Troubleshooting Challenges:* Without logs that clearly indicate whether Crypto
AES is enabled or disabled, diagnosing issues related to encrypted
communication becomes significantly harder. In the event of a communication
failure or performance issue, the lack of logs may hinder root cause analysis,
delaying resolution.
#
*Unintended Configuration Behavior:* If the configuration is altered or
misconfigured (e.g., Crypto AES is inadvertently disabled), the absence of logs
makes it difficult to confirm that the system is operating as intended. This
could lead to security vulnerabilities or unexpected behavior that goes
unnoticed.
*Expected Behavior:*
Enhanced logging should provide clear insights into the configuration state of
Crypto AES during the establishment of the connection header: *
If Crypto AES is enabled, the system should log the setup of the Cipher
transformation, including the key and default value.
*
If Crypto AES is disabled, the system should log this state, ensuring that the
administrator is aware and that this is the intended configuration.
*How-to-Fix:*
To address these issues, the code can be enhanced by inserting specific log
statements that capture the state of the Crypto AES configuration. These logs
should be added right before the Cipher transformation is set up or bypassed,
ensuring that the configuration's impact on the system is well-documented.
