------------------------------
Summary: Unnecessary INFO logging on DFSClients for InvalidToken
Key: HDFS-11012
URL: https://issues.apache.org/jira/browse/HDFS-11012
Project: Hadoop HDFS
Issue Type: Improvement
Components: fs
Affects Versions: 2.5.0
Reporter: Harsh J
Assignee: Harsh J
Priority: Minor
In situations where a DFSClient would receive an InvalidToken exception (as
described at [1]), a single retry is automatically made (as observed at [2]).
However, we still print an INFO message into the DFSClient's logger even though
the message is expected in some scenarios. This should ideally be a DEBUG level
message to avoid confusion.
If the retry or the retried attempt fails, the final clause handles it anyway
and prints out a proper WARN (as seen at [3]) so the INFO is unnecessary.
