Description

2016-08-05 14:42:04,687 ERROR org.apache.hadoop.hdfs.server.namenode.NameNode: FSDirectory.verifyMaxDirItems: The directory item limit of null is exceeded: limit=1048576 items=1048576

The error message above logs the path name incorrectly (null). Without the path name it is hard to tell which directory is in trouble. The exception should set the path name before being logged.

This bug was seen on a CDH 5.5.2 cluster, but CDH5.5.2 is roughly up to date with Apache Hadoop 2.7.2.
