Josh Elser created HDFS-5856: -------------------------------- Summary: DataNode.checkDiskError might throw NPE Key: HDFS-5856 URL: https://issues.apache.org/jira/browse/HDFS-5856 Project: Hadoop HDFS Issue Type: Bug Components: datanode Affects Versions: 2.2.0 Reporter: Josh Elser Assignee: Josh Elser Priority: Minor Fix For: 3.0.0
Running a small 2.2.0 cluster with a heavy workload. I noticed in the DataNode log that when faced with network exceptions, I would sometimes get a NullPointerException from checkDiskError. Looking at the code, if the Exception that is handed to checkDiskError contains a null message, the checks that try to identify if the Exception is network-related will throw a NPE. -- This message was sent by Atlassian JIRA (v6.1.5#6160)
