Hadoop Flags: Incompatible change,Reviewed (was: Reviewed)
Release Note: This removes the configuration property
{{dfs.client.use.legacy.blockreader}}, since the legacy remote block reader
class has been removed from the codebase. (was: This will obsoletes this
configuration property, since the legacy block reader is removed from the code
base. {{dfs.client.use.legacy.blockreader}})
I also realized on second inspection that the LEGACY_BLOCKREADER config key is
still present in HdfsClientConfigKeys and DFSConfigKeys. How do we feel about
removing it?
