> The original patch for
> [Hadoop-8235|https://issues.apache.org/jira/browse/HADOOP-8235] contained a
> bug for ‘chmod’ implantation. The logic to compute new access mask when
> ‘chmod’ mode string has ‘=’ in them is incorrect. For example, ‘winutils
> chmod o=g foo’ will result wrong permission settings for the file ‘foo’. The
> Jira is created to track the bug.
