----------------------------------------
Summary: Support fetching multiple DFS tokens for HDFS Federation
Key: GOBBLIN-1286
URL: https://issues.apache.org/jira/browse/GOBBLIN-1286
Project: Apache Gobblin
Issue Type: Improvement
Components: misc
Reporter: Sandeep Devaiah
Currently org.apache.gobblin.util.hadoop.TokenUtils#getHdfsToken adds the
DistributedFileSystem's delegation token to the Credential's object. However,
if the DFS is federated, then only one token for the primary name node is
fetched and tokens for child namenodes are not fetched.
Hence this method needs to be updated to use
org.apache.hadoop.fs.FileSystem#addDelegationTokens instead of
org.apache.hadoop.fs.FileSystem#getDelegationTokens which automatically fetches
the delegation tokens for all child FS as well.
