Summary: Add FileBasedSource lineage event
Key: GOBBLIN-716
URL: https://issues.apache.org/jira/browse/GOBBLIN-716
Project: Apache Gobblin
Issue Type: Bug
Reporter: Zhixiong Chen
Assignee: Zhixiong Chen
It'd be useful to support configuration properties to override the default
username when connecting to a HDFS cluster, e.g. in the HDFS writers. The
system username that owns the Gobblin process is used by default.
One particular use case for this is for stand-alone Gobblin instances running
as the `root` system user within a Docker container. Individual users within
an organization employing a stand-alone Gobblin cluster for data integration
needs across multiple teams may have multiple users submitting jobs meant to
touch different parts of the HDFS namespace under the control of separate users.
Note that this feature is not quite security-relevant, as this would still
allow any job configuration file to specify any username, so there aren't any
enforced privilege boundaries anyway.
One solution that does not appear to work is to specify the `hadoop.job.ugi`
property in a job configuration file, despite what this appears to suggest in
[FsDataWriter.java](https://github.com/linkedin/gobblin/blob/7141ec88c255c8c3cbc7054fb8146eebe77fc09d/gobblin-core/src/main/java/gobblin/writer/FsDataWriter.java#L88-L91):
```java
Configuration conf = new Configuration();
// Add all job configuration properties so they are picked up by Hadoop
JobConfigurationUtils.putStateIntoConfiguration(properties, conf);
this.fs = WriterUtils.getWriterFS(properties, this.numBranches,
this.branchId);
```
