Ming Ma created HDFS-6272: ----------------------------- Summary: Improve FSNamesystem.listCorruptFileBlocks so that it doesn't need to acquire the readLock. Key: HDFS-6272 URL: https://issues.apache.org/jira/browse/HDFS-6272 Project: Hadoop HDFS Issue Type: Improvement Reporter: Ming Ma
FSNamesystem.listCorruptFileBlocks currently needs to take readLock to enumerate the list of corruptFileBlocks. The call will be blocked if NN's writeLock is owned by another thread. It will be useful if FSNamesystem.listCorruptFileBlocks doesn't require readLock for scenarios like JMX. -- This message was sent by Atlassian JIRA (v6.2#6252)
