Description

In one of our customer's cluster, we saw the NameNode kept printing out the following error msg and thus got stuck for several minutes:

ERROR org.apache.hadoop.hdfs.server.namenode.FSNamesystem: Swallowing exception in NameNodeEditLogRoller:
java.lang.IllegalStateException: Bad state: BETWEEN_LOG_SEGMENTS
