---------------------------------
Summary: PutHDFS does not use fs.permissions.umask-mode from
hdfs-site.xml
Key: NIFI-5575
URL: https://issues.apache.org/jira/browse/NIFI-5575
Project: Apache NiFi
Issue Type: Bug
Components: Extensions
Affects Versions: 1.7.1
Reporter: Jeff Storck
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}
