--------------------------------------
Summary: Fix up yarn top shell code
Key: YARN-3484
URL: https://issues.apache.org/jira/browse/YARN-3484
Project: Hadoop YARN
Issue Type: Bug
Components: scripts
Affects Versions: 3.0.0
Reporter: Allen Wittenauer
We need to do some work on yarn top's shell code.
a) Just checking for TERM isn't good enough. We really need to check the
return on tput, especially since the output will not be a number but an error
string which will likely blow up the java code in horrible ways.
b) All the single bracket tests should be double brackets to force the bash
built-in.
c) I'd think I'd rather see the shell portion in a function since it's rather
large. This will allow for args, etc, to get local'ized and clean up the case
statement.
