> NPE thrown if an IOException is thrown in NameNode.<init>

> Key: HDFS-9249
> URL: https://issues.apache.org/jira/browse/HDFS-9249
> Project: Hadoop HDFS
> Issue Type: Bug
> Reporter: Wei-Chiu Chuang
> Assignee: Wei-Chiu Chuang
> Priority: Minor
> Labels: supportability
> Attachments: HDFS-9249.001.patch
>
>
> This issue was found when running test case
> TestBackupNode.testCheckpointNode, but upon closer look, the problem is not
> due to the test case.
> Looks like an IOException was thrown in
> try {
> initializeGenericKeys(conf, nsId, namenodeId);
> initialize(conf);
> try {
> haContext.writeLock();
> state.prepareToEnterState(haContext);
> state.enterState(haContext);
> } finally {
> haContext.writeUnlock();
> }
> causing the namenode to stop, but the namesystem was not yet properly
> instantiated, causing NPE.
> I tried to reproduce locally, but to no avail.
> Because I could not reproduce the bug, and the log does not indicate what
> caused the IOException, I suggest make this a supportability JIRA to log the
> exception for future improvement.
