Using Named Pipes

As of version 2.1.2, MapR supports using named pipes over NFS. This feature is enabled by default in new installations of versions 2.1.2 and above; for upgrades, enable the feature manually by setting mfs.feature.devicefile.support to 1 using the maprcli config save command.

maprcli config save -values '{"mfs.feature.devicefile.support":"1"}'

To disable the feature, set mfs.feature.devicefile.support to 0.
