> Project: Apache NiFi
> Issue Type: Bug
> Components: Extensions

> PutHDFS does not use the value of "fs.permissions.umask-mode" in hdfs-site.xml. If the user does not provide a umask in the "Permissions umask" property, PutHDFS will use FsPermissions.DEFAULT_UMASK and set that in the config, which will overwrite the value from hdfs-site.xml.
> The code below shows that without the "Permissions umask" property being set, it will force a umask of '18', the value of FsPermission.DEFAULT_MASK.
> Instead, PutHDFS should first check the Configuration instance to see if "fs.permissions.umask-mode" is set and use that value. FsPermission.DEFAULT_MASK should be used only in the case when "fs.permissions.umask-mode" is not set.
> {code:java}
> protected void preProcessConfiguration(final Configuration config, final ProcessContext context) {
> // Set umask once, to avoid thread safety issues doing it in onTrigger
> final PropertyValue umaskProp = context.getProperty(UMASK);
> final short dfsUmask;
> if (umaskProp.isSet()) {
> dfsUmask = Short.parseShort(umaskProp.getValue(), 8);
> } else {
> dfsUmask = FsPermission.DEFAULT_UMASK;
> }
> FsPermission.setUMask(config, new FsPermission(dfsUmask));
> }
> {code}
