---------------------------------
Summary: TestCheckpoint#testSecondaryHasVeryOutOfDateImage
occasionally fails due to unexpected exit
Key: HDFS-4006
URL: https://issues.apache.org/jira/browse/HDFS-4006
Project: Hadoop HDFS
Issue Type: Bug
Components: name-node
Affects Versions: 2.0.0-alpha
Reporter: Eli Collins
TestCheckpoint#testSecondaryHasVeryOutOfDateImage occasionally fails due to
unexpected exit, due to an NPE while checkpointing. It looks like the
background checkpoint fails, conflicts with the explicit checkpoints done by
the tests (note the backtrace is not for the doCheckpoint calls in the tests.
