> FsDatasetSpi.isValidBlock() lacks null pointer check inside and neither do
> the callers
> --------------------------------------------------------------------------------------
>
> Key: HDFS-12487
> URL: https://issues.apache.org/jira/browse/HDFS-12487
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: balancer & mover, diskbalancer
> Affects Versions: 3.0.0
> Environment: CentOS 6.8 x64
> CPU:4 core
> Memory:16GB
> Hadoop: Release 3.0.0-alpha4
> Reporter: liumi
> Assignee: liumi
> Fix For: 3.1.0
>
> Attachments: HDFS-12487.002.patch
>
> Original Estimate: 0h
> Remaining Estimate: 0h
>
> BlockIteratorImpl.nextBlock() will look for the blocks in the source volume,
> if there are no blocks any more, it will return null up to
> DiskBalancer.getBlockToCopy(). However, the DiskBalancer.getBlockToCopy()
> will check whether it's a valid block.
> When I look into the FsDatasetSpi.isValidBlock(), I find that it doesn't
> check the null pointer! In fact, we firstly need to check whether it's null
> or not, or exception will occur.
> This bug is hard to find, because the DiskBalancer hardly copy all the data
> of one volume to others. Even if some times we may copy all the data of one
> volume to other volumes, when the bug occurs, the copy process has already
> done.
> However, when we try to copy all the data of two or more volumes to other
> volumes in more than one step, the thread will be shut down, which is caused
> by the bug above.
> The bug can fixed by two ways:
> 1)Before the call of FsDatasetSpi.isValidBlock(), we check the null pointer
> 2)Check the null pointer inside the implementation of
> FsDatasetSpi.isValidBlock()
