----------------------------------
Summary: Add Logging for Long-held NN Read Locks
Key: HDFS-10817
URL: https://issues.apache.org/jira/browse/HDFS-10817
Project: Hadoop HDFS
Issue Type: Improvement
Components: logging, namenode
Reporter: Erik Krogen
Assignee: Erik Krogen
Right now the Namenode will log when a write lock is held for a long time to
help tracks methods which are causing expensive delays. Let's do the same for
read locks since these operations may also be expensive/long and cause delays.
