> Namenode crash caused by NPE in BlockPlacementPolicyDefault when dynamically
> change logger to debug
> ---------------------------------------------------------------------------------------------------
>
> Key: HDFS-15115
> URL: https://issues.apache.org/jira/browse/HDFS-15115
> Project: Hadoop HDFS
> Issue Type: Bug
> Reporter: wangzhixiang
> Assignee: David Mollitor
> Priority: Major
> Attachments: HDFS-15115.001.patch, HDFS-15115.003.patch,
> HDFS-15115.2.patch
>
>
> To get debug info, we dynamically change the logger of
> BlockPlacementPolicyDefault to debug when namenode is running. However, the
> Namenode crashs. From the log, we find some NPE in
> BlockPlacementPolicyDefault.chooseRandom. Because *StringBuilder builder*
> will be used 4 times in BlockPlacementPolicyDefault.chooseRandom method.
> While the *builder* only initializes in the first time of this method. If we
> change the logger of BlockPlacementPolicyDefault to debug after the part, the
> *builder* in remaining part is *NULL* and cause *NPE*
