> Key: HADOOP-12164
> URL: https://issues.apache.org/jira/browse/HADOOP-12164
> Project: Hadoop Common
> Issue Type: Bug
> Affects Versions: 2.7.0
> Reporter: Lei (Eddy) Xu
> Assignee: Lei (Eddy) Xu
> Priority: Minor
> Fix For: 3.0.0, 2.8.0
>
> Attachments: HADOOP-12164.000.patch

>
> When enabled {{hadoop.shell.missing.defaultFs.warning}}, a few tests were
> failed as following:
> {noformat}
> java.lang.RuntimeException: failed to get .NAME
> at java.lang.Class.getDeclaredField(Class.java:1948)
> at org.apache.hadoop.fs.shell.Command.getCommandField(Command.java:458)
> at org.apache.hadoop.fs.shell.Command.getName(Command.java:401)
> at
> org.apache.hadoop.fs.shell.FsCommand.getCommandName(FsCommand.java:80)
> at
> org.apache.hadoop.fs.shell.FsCommand.processRawArguments(FsCommand.java:111)
> at org.apache.hadoop.fs.shell.Command.run(Command.java:154)
> at
> org.apache.hadoop.fs.TestFsShellReturnCode.testChgrpGroupValidity(TestFsShellReturnCode.java:434)
> {noformat}
> The reason is that, in {{FsCommand#processRawArguments}}, it uses
> {{getCommandName()}}, which uses reflection to find {{static String NAME}}
> field, to build error message. But in the tests, the commands are built
> without {{static String NAME}} field, since it is not inherited.
