    Details

    • Hadoop Flags:
      Reviewed
    • Release Note:
      The presence of HDFS short-circuit read configuration properties in hbase-default.xml inadvertently causes short-circuit reads to not happen inside of RegionServers, despite short-circuit reads being enabled in hdfs-site.xml.

      Description

      I think this parameter is not suitable for in hbase-default.xml, because in this case, HDFS explicitly set to "dfs.client.read.shortcircuit=true", hbase rely on HDFS configuration, the parameters in hbase service still is false.Must be explicitly in hbase-site.xml is set to "dfs.client.read.shortcircuit=true" to take effect.The same goes for the parameter 'dfs.domain.socket.path', which is already covered in the specific change.
