> 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].
