> The {{package org.apache.hadoop.hdfs.protocol.datatransfer.PipelineAck}} class is used
in client module classes (e.g. {{DataStreamer$ResponseProcessor}} in {{DFSInputStream}} and
{{DFSOutputStream}}). This jira tracks the effort of moving this class to {{hadoop-hdfs-client}}
module.
> We should keep the static attribute {{OOB_TIMEOUT}} and helper method {{getOOBTimeout}}
in the {{hadoop-hdfs}} module as they're not used (by now) in {{hadoop-hdfs-client}} module.
Meanwhile, we don't create the {{HdfsConfiguration}} statically if we can pass the correct
{{conf}} object.
> The checkstyle warnings can be addressed in [HDFS-8979|https://issues.apache.org/jira/browse/HDFS-8979].
