------------------------------------
Summary: Incorrect null value check
Key: HDFS-13261
URL: https://issues.apache.org/jira/browse/HDFS-13261
Project: Hadoop HDFS
Issue Type: Bug
Components: hdfs
Affects Versions: 3.0.0, 2.8.3
Reporter: Jianfei Jiang
Assignee: Jianfei Jiang
{code:java}
public void setZoneName(final String name) {
Preconditions.checkNotNull(name == null)-------error parameter for
checkNotNull
zoneName = name;
}
{code}
Like above, in 3.x, the checkNotNull function gets wrong parameter in two
cases: \{{ZoneReencryptionStatus#setZoneName}} and
\{{AdminHelper#HelpCommand#HelpCommand}}
In 2.x, the error occurs once in \{{AdminHelper#HelpCommand#HelpCommand}}
