> Key: HDFS-4590
> URL: https://issues.apache.org/jira/browse/HDFS-4590
> Project: Hadoop HDFS
> Issue Type: Test
> Components: hdfs-client
> Affects Versions: 1.2.0
> Environment: Java Unit Test Case
> Reporter: Huned Lokhandwala
> Priority: Minor
>
> Add more Java Unit Test Coverage for the feature HDFS-3701 where the file is
> opened for writing, the DFSClient calls one of the datanode owning the last
> block to get its size. If this datanode is dead, the socket exception is
> shallowed and the size of this last block is equals to zero. Add a unit test
> case to write to a file, shutdown the datanodes, and then try to read from
> the file and expect an Exception. On 1.1.0 it will produce the exception as
> expected, but on 1.0.3 it will return a file length of zero after read.
