Description

This jira tracks the effort of moving the RemoteBlockReader class into the hdfs-client module. BlockReader interface and BlockReaderLocal class were moved to hadoop-hdfs-client module in jira HDFS-8925.

The extant checkstyle warnings can be fixed in HDFS-8979. While we need to replace the log4j with slf4j in this patch, we track the effort of removing the guards when calling LOG.debug() and LOG.trace() in jira HDFS-8971.
