nijel created HDFS-9162:
---------------------------
Summary: [OIV and OEV] : The output stream can be created only if
the processor value specified is correct, if not return error to user.
Key: HDFS-9162
URL: https://issues.apache.org/jira/browse/HDFS-9162
Project: Hadoop HDFS
Issue Type: Sub-task
Reporter: nijel
Assignee: nijel
In both tools, the output file will be overwritten, if it exists.
Now if user passes invalid processor value, the file content will be lost.
in this case the PrintStream is created before checking the processor options.
So the output file will be empty even if the command fails.
The output stream can be created only if the processor value specified is
correct, if not return error to user.
