Kevin Geiszler commented on HBASE-29761:
----------------------------------------
I looked into this more and found the issue.
Both {{MasterDumpServlet}} and {{RSDumpServlet}} initially call conf.writeXml()
with `this` method signature:
[writeXml(OutputStream
out)|https://github.com/apache/hadoop/blob/trunk/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/conf/Configuration.java#L3576]
This starts a chain of calling other Configuration.writeXml() methods.
Eventually, we see this one get called:
[writeXml(@Nullable String propertyName, Writer
out)|https://github.com/apache/hadoop/blob/trunk/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/conf/Configuration.java#L3629]
The problem is when this version of the method is runs, the next writeXml()
method it calls is receiving null as the value for the conf arg. This results
in the ConfigRedactor object being null, which happens
[here|https://github.com/apache/hadoop/blob/trunk/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/conf/Configuration.java#L3611].

> Priority: Critical

> The Debug Dump feature in the HBase UI is supposed to redact sensitive
