------------------------------------
Summary: NN logs unnecessary
org.apache.hadoop.hdfs.protocol.UnresolvedPathException
Key: HDFS-7233
URL: https://issues.apache.org/jira/browse/HDFS-7233
Project: Hadoop HDFS
Issue Type: Bug
Affects Versions: 2.5.1
Reporter: Rushabh S Shah
Assignee: Rushabh S Shah
Namenode logs the UnresolvedPathExceptioneven though that file exists in HDFS.
Each time a symlink is accessed the NN will
throw an UnresolvedPathException to have the client resolve it. This shouldn't
be logged in the NN log and we could have really large NN logs if we
don't fix this since every MR job on the cluster will access this symlink and
cause a stacktrace to be logged.
