Todd Lipcon created HDFS-3656: --------------------------------- Summary: ZKFC may write a null "breadcrumb" znode Key: HDFS-3656 URL: https://issues.apache.org/jira/browse/HDFS-3656 Project: Hadoop HDFS Issue Type: Bug Components: auto-failover Affects Versions: 2.0.0-alpha Reporter: Todd Lipcon
A user [reported|https://issues.cloudera.org/browse/DISTRO-412] an NPE trying to read the "breadcrumb" znode in the failover controller. This happened repeatedly, implying that an earlier process set the znode to null - probably some race, though I don't see anything obvious in the code. -- This message is automatically generated by JIRA.
